Adds a BuddyPress tab to the add new plugins admin page that includes a list of curated BuddyPress plugins.

BuddyPlug

The curated list is now stale really stale and the report broken plugin link 404s. Interesting though for uderstanding how the plugin api and list tabel work (by looking at their code).

Happily give it 5 stars if it was kept up to date

Great idea but

Quickly and easily access and install BuddyPress plugins from WordPress.org, right from your dashboard.
