@sharmavishal,

hi captain Haddock, i’m not in charge of a plugin list. 🙂 And latest information about this missing page can be found here.

Actually, the only place to get a list of BP plugins is the WP repository.

If you don’t want to miss specifically imath’s plugins, you can subscibe to his twitter account(@imath), or for any other plugin author, a solution could be to subscribe to WP plugins feed.
