If you want to completely disable public registrations, and only want to set up a invite only BuddyPress community, check out this plugin as well: https://wordpress.org/extend/plugins/wordpress-mu-secure-invites/
Should work in combination with the plugin Mercime mentioned 
1) You could import/export all posts and comments from LJ to WordPress site. https://codex.wordpress.org/Importing_Content#LiveJournal. Didn’t check what WP version the script was compatible with, but you can download WP versions from this page
and upgrade to later version later.
https://wordpress.org/download/release-archive/
Currently, there are no scripts to convert these into a BuddyPress group setting. You might have to hire someone to consult with or to implement that as well as import users automagically as BP/WP users along the way.

#2 and #3. Haven’t seen any indication that this can be done except probably with RSS imports/exports. I suggest you clear up #1 first before moving along these questions.

Ooh! Very cool… I was going to start playing around with the idea for my theme too. But I’ll wait for your plugin which will likely be infinitely more robust than my n00b brain could churn out 
I just went though every post and do not see anybody with a problem mentioning whether you are working with sweet potatoes or white potatoes. Just to mention that they are not the same thing, not even close, and the same refers to Apachi vs. MS IIS.
I’m running Win 2008r2 Server with IIS7.5 (key information), any BuddyPress links are missing index.php in the url. Does anyone have a solution for this case (plese do not tell me that I need to enable mod_rewrite or any other silly thing)
Thank you,
Waldis
Hi,
I looked at your site, and it looks like you’ve figured it out. Would you share your solution?
I see hundreds of posts with this problem for buddypress running under IIS not adding index.php in the link, but most of the people just throw at you suggestions without reading posts – mainly they fail to understand that IIS is not the same as Apachi.
Thanks,
Waldis
= I found some article and plugin for custimizing WP theme for BP ==
That’s one way, using your WordPress theme and installing the BP Template Pack plugin to transfer BP template files (for BP component pages) plus ajax and js goodness to make your WP theme BP-compatible.
Another way is to create a child theme of the bp-default theme
https://codex.buddypress.org/theme-development/building-a-buddypress-child-theme/
then adjust via CSS only to change layout and colors or do more than that.
@nahummadrid – This is a known bug. Using bp_core_remove_nav_item() will remove access to those pages as well. Right now, I’d suggest hiding the nav item via CSS or by hacking the $bp global to remove the item.
@shanebp, @nahummadrid – The problem is BP Follow uses an older method to add items to the nav. The plugin needs to be updated to use the newer BP conventions; I’m thinking of asking Andy for contributor access.
In the meantime, you need to make sure your code runs after BP Follow.
Change:
`add_action( ‘bp_setup_nav’, ‘sc_remove_nav_tabs’, 15 );`
to
`add_action( ‘init’, ‘sc_remove_nav_tabs’, 15 );`
And it should work.
No it was my bad @hnla, in the process of editing the code that mdanista posted above because it was not showing up then wreaking havoc to the layout, I placed the wrong edit topic code and @gregfielding‘s got edited. To compound the problem, I tried to move greg’s topic and it looks like it was deleted instead. Sorry Greg!
@gregfielding did you post in the wrong thread ? 
The project is far from abandoned, for an open source project it’s doing nicely for development.
Please learn to appreciate something that is free.
Check out the Trac to see the state of development. There are three core developers with commit privileges they do all the work – mostly – and they work on a voluntary basis as this an OS project, members also help to move it forward and the speed at which it does develop is largely governed by the effort we all put in and other than the main three developers not many of us are contributing at the moment!
As for themes ? what do you want, again these are written on a voluntary basis and themes for BP are of a magnitude harder than a bog standard WP layout and are not a trivial matter and take time, but there are themes around if you look.
So no the project isn’t abandoned.
Was the BuddyPress project abandoned? It has no decent themes, plugins are not updated, several errors presented from several months ago with no solution…
== I can no longer reach the main index template from the editor as a Network Admin ==
If you mean files in child theme of bp-default theme, that has been reported
https://trac.buddypress.org/ticket/3096
https://core.trac.wordpress.org/ticket/16744
If on other themes, please provide more information or steps to replicate problem.
That search has been down for awhile, as I think @johnjamesjacoby may be working on it.
Searching on codex.buddypress.org is not working for me:
http://codex.buddypress.org/?s=multisite
I would appreciate if someone can explain me theme usage.As I understand buddypress requires special theme. I found some article and plugin for custimizing WP theme for BP but plugin is not working with WP 3.1. Do you use separate themes for WP and BP or you adjust main theme?
Tnx
1) Is it possible to import all posts in LJ community to my BuddyPress group? And with comments tree?
2) Is it possible not only import but regular updating this BuddyPress group from LJ community new writings? By using RSS-import plugins I suppose?
3) Is there any solutions for crossposting between LJ and BuddyPress blog (and group)? And between separate WordPress blog and BuddyPress one?
already was able to get one avatar with the code below, only don’t know how to add multiple IDs to bp_core_get_userid( ‘1’ ), but your method works well @mercime, somehow I forgot about this loop, thanks a lot!
`
<a href="” title=””> $member_id, ‘type’ => ‘thumb’ ) ) ?>`
An easier alternative would be to use the member’s loop to generate your list:
`
Featured Members
<a href="”>
`
where 2,12,46,233,365 are the user ID’s of the people you want to feature.

Hi there, I recently installed Buddypress on multisite and found out that I can no longer reach the main index template from the editor as a Network Admin. Instead of the code for my original index (the one from the theme previous to the installation), now I find a different code that’s from Buddypress.
The site is running as it should, but I can’t edit the main index. Was the code moved to some other place in my server or what?
hi @mercime ,
thanks for reply. yes, idea was to use this plugin, but it has some strange issue with last wp bp updates described here: https://buddypress.org/community/groups/buddypress-featured-members-widget/forum/topic/multiple-avatars-of-the-same-member-showing-in-widget/
therefor, I hoped that there is some other approach.
Hello,
I’ve searched and searched the Net but not found an answer… also, I’m a novice when it comes to php. I work mainly as a designer and frontend coder…
I have a World of Warcraft community site that runs on Buddypress. I want users to be able to import their WoW character(s) into their profile and (choose to) display them as part of their profile… for starters.
I know part of the answer to my question requires me to learn more php. I’m doing so now. I also know that the WoW armory has an xml feed that one can scrape. I need to know how to scrape it and how to add that to the user’s profile as an option.
If anyone reading this can help in any way I’d surely appreciate it.
Eventually I want to turn this into a plugin.
Thanks,
DC
