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

Works just fine on latest WordPress, even under Mercury child theme, although I'll have to do some styling for the avatars of those who liked a post or comment (they get slightly cropped on the right side).

Nice!

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!
