BuddyPress is considered off-topic for WPSE. However, it is a big ecosystem in its own right and has a lot of third party development going on. Perhaps WPSE would be somewhat less overwhelmed if BuddyPress questions could be migrated to another stack (one just for BuddyPress development).
If enough of us think this is a good idea, I will propose the new stack.
Who is willing to yes to this in principle?
Edit: If this is to be done, I mean to see it done well. This meta is not the only place I have posted the proposal. I've also posted on a WordPress dev blog I write for and (more importantly) in the BuddyPress forums.
