Simple widget to extend P2s (and other themes) functionality and display recent @replies for a logged in user in the sidebar. 
It can be also configured to show direct replies to comments or posts without the @username indication.

Mention-Me Widget

11-year old plugin and it still works just fine! Sweet!

It works!

P2 Likes brings Facebook-like functionality to your P2 site. Your users can now show interest in threads by clicking the like button.

P2 Likes

Nice!
