Reply To: Group Post support
BuddyPress is a plugin dedicated to members, not blogs. On a multisite install, each member can get his separate blog, without limitation. These member blogs are then refrenced on a blog directory. An each membrer profile will show a blog directory with that member’s blog(s).
Groups is a component to group members, not blogs. If you need a group blog, instead or in addition of individual member blogs, you can use BuddyPress Groupblog. Such blog will be for all group members and each group can have only one blog. But each group member can have his own blog. In this case, the network will have a main blog, group blogs and individual blogs.
Whatever solution you use, a blog is always part of WordPress and will work exactly like the main site blog where you installed BuddyPress.
This means that it’s the responsability of each member with a blog to admin his blog, even if the main site admin has priority and can allow/disallow plugins and themes. Usually disallowed, so members can only use what main site admin decided they can use.
Enhancement can be asked on Trac. Read here about user participation and contribution to BuddyPress.
