MyBB Source

Hey
I have noticed these:

http://mybbsource.com/userbar.php?uid=1

I was wondering what modification this is?

And also is it just for forum profiles or is their a version for whole forums? (Ex. Shows threads, members, posts etc.. of a forum)

This particular modification can be found here and its subscriber only so you would need to pay 5$ to get it (including other exlusive plugins).
There is also the "whole" forums version whic can be found here and its also an subscriber only and you would have to pay 10$ to get it (including other exclusive plugins).

The only "free" sollution is to get someone to do it for you like I did
