Friend/Follower addon

Do you know any jquery? Because with jQuery and Ajax you can do this (not so difficult). But start with creating another database table for this operation:

fav_id   - follower_id  - followed_id 

and use the power of jquery/ajax.

Oh yeah I know jquery...I use it alot in my basic html sites. I've seen quite a bit of ajax based scripts and in the process of adding one in my site now! Thanks for the advice
