BuddyPress doesn’t do anything for blogs except track new blog posts and comments in the activity stream.
WordPress handles all blog creation. If you want your users to be able to create blogs, you’ll first need to change your WordPress install into a network:
https://codex.wordpress.org/Create_A_Network
Be sure to read the “Do you really need a network?” section as well:
https://codex.wordpress.org/Create_A_Network#Do_you_really_need_a_network.3F
If you just want your users to contribute to your existing WordPress blog, then you’ll need to make your users authors:
https://codex.wordpress.org/Users_Screen

There’s a WordPress theme called P2:
http://p2theme.com/
It’s not compatible with BuddyPress though, however there is a fork of P2 (called P2 Reloaded) that reportedly supports BuddyPress:
http://p2reloaded.com/2011/07/3-0-beta-release/
I haven’t tested it myself.
Hi FIQ, you might want to post this as a bug on BP Trac:
https://buddypress.trac.wordpress.org/newticket/
Login with the same credentials you use here on bp.org.
[RESOLVED for now]
There’s a suggestion here that selects “no” by default: https://wordpress.org/support/topic/plugin-group-documents-notification-disabled-by-default.
Didn’t work for me though. What I did instead is comment out the function that actually sends the email notifications in notificiations.php. Just add “*/” (minus the quotes) at the bottom of the file. Assuming that you haven’t altered the file in any way yet.
Thank you, but still having problems. 
I removed everything from the server and started over. I completed the BuddyPress Setup steps and when I clicked Finish & Activate I got the same 500 error.
Afterwards I updated wp-config.php, the .htaccess file, & upped the memory limits for the site. I tried in different browsers, but to no avail. I don’t have access to my php.ini file, so I’m hoping that’s not the problem. The site seems to be working fine, but the dashboard is still not functional.
Here are the errors I got from the error log:
[Thu Feb 09 18:21:21 2012] [warn] mod_fcgid: stderr: PHP Fatal error: Call to undefined function bp_is_active() in /home/httpd/vhosts/mydomain.com/httpdocs/wp-content/plugins/buddypress/bp-core/admin/bp-core-admin.php on line 45

Please forgive my idiocy, but I have no clue what to make of that. Please help! 
Are you able to tell what the problem is from those error logs?
Thanks again!
The theme developer has responded and does need more assistance because the navigation and website header are missing.
The them developer has applied the changes you suggested. If you go back to the test website http://buddypress.centennialchristianchurch.com/
and view the only navigation menu pages, the website header and navigation bar are removed.
I don’t know of anything specific you can do about completely deleted pages. I try to avoid them.
Having a google sitemap.xml file might help. I use: https://wordpress.org/extend/plugins/google-sitemap-generator/ but there are others…..
Single WP install, sure. Just add the categories from backend and users can only choose from the available categories.
If you’re talking about categorizing a multisite blog, you could use something like this https://wordpress.org/extend/plugins/blog-topics/
Or if you’re looking to create categories in main site which are automatically added to new subsites of multisite install http://wordpress.stackexchange.com/questions/12201/wordpress-multisite-global-categories
For a few individual pages you could just add redirect rules, a line per rule, to your .htaccess file – something like:
`
Redirect 301 /oldpage/ http://domain.com/newpage/
`
The old page address is from the site root (the same as the htaccess file) the new address has to be from http://
The following discussion might be useful http://wordpress.stackexchange.com/questions/8665/how-to-301-redirect-category-to-customname
can i create a child theme in the bottom of my already created wordpress style.css?
i want to know that before i follow the instruction of the child theme becose i already have a style.css and i don’t know where to start: https://codex.buddypress.org/theme-development/building-a-buddypress-child-theme/
If not, can i create two style.css my already created style.css and a new one for buddypress?
== i just want to know if buddypress has a easy way to change the colours ==
You mean you want to create a child theme of bp-default theme and make it look like Motion theme? Change colors via child theme’s stylesheet.
If that’s not what you meant .. the theme used in the BP Template Pack walkthrough is a WP theme which you can download https://wordpress.org/extend/themes/motion That example was done some time ago, so if you find different divs in the new version of Motion theme, feel free to ask for assistance here.
Theme author of Suffusion theme has a created a plugin to make Suffusion compatible with BuddyPress, so you don’t need to install and activate BP Template Pack plugin
https://wordpress.org/extend/plugins/suffusion-buddypress-pack/
No, set WPLANG to ‘el’, just like if you weren’t using BuddyPress. You can’t define WPLANG twice, it won’t work. You’ll need a WordPress translation loaded, as well as a BuddyPress one.
1. Anything’s possible. You’ll just need to build it. BuddyPress doesn’t handle authentication, that’s all down to WordPress (so, if you can get it working with WordPress…).
2. By default, any user can see any user’s activity. You’ll either want to build some sort of bespoke privacy control, or see if you can get s2member (plugin) configured to work like this.
3. Anything’s possible. BuddyPress 1.6 will have built-in integration for the Activity component with Akismet, which might help get you started. bbPress 2.x also has built-in integration for Akismet.
4. Yes, it scales. Research into how to scale WordPress up to your expected levels of users.
Have you tried installing https://wordpress.org/extend/plugins/wp-mail-smtp/ then sending a test email from the settings page?
The debug information should indicate where the problem is and the error codes can be googled for further info if necessary….
