BuddyPress.org

Hi!
Sorry, didn’t see your answers.
So after few hours, I did it.
Simply use the plugin https://wordpress.org/plugins/external-group-blogs/ (thx @mercime)
Then use a RSS parser http://simplepie.org/
The plugin structure is mainly the same, I use the admin area as base, then add a new tab if the group meta “feed-url” is not empty, an finaly load my rss parser function into the groups/single/plugins.php

Add some php to fetch image in feeds thumbnail (if exists) or in enclosure link (if exists) or feeds content.
The result is I expected. Largely copied on feedly 😉

Here is what it looks for the moment: http://www.gumdust.com/groups/bsp-team/blog-rss-feed/

Hope this help!

yes, i know, that is the problem that i’m having and of course why i can’t use it. you just keep bringing up the same issue. i’m well aware of what it does and does not do. been using it for years. it’s why i asked the question in the first place, just to see if things have changed in 1.8.1. i have already acknowledged that i know you can use buddypress on multisite but each site on my network is it’s own community and the subject of each is different, so it defeats the purpose to have all network-wide activity in one place. And it’s a fact that every site on the network is wordpress based, uses all of the same plugins and definitely could be running on a single network if Buddypress would work on each site individually. I know there is value in the way that BP works currently on multisite, some people prefer it, but i’m not the only one that would also like it to function independently on each site as well. Would be a great feature to have. Not holding my breath though, decided that 2 years ago. I currently use ManageWP to manage all sites or it would be impossible to do with my current staff.
