I’m tagging tickets in Trac that would make good plugins. If you’re looking to create a new BuddyPress plugin, please keep checking this list.
Also, if you submit new ideas for BuddyPress in Trac, please add the “plugin” keyword. The best way for new features to make it into BuddyPress quickly is to make a great plugin that could eventually be merged into the core if it makes sense.

If you decide to build one of these ideas, please write a note on the ticket.
