Classify users by usergroup.

[Y@M]

Hello all!
I still no know how vBulletin not think about that yet.
I want that in my forum, in the bottom, where you see all the users, it's will be classify according to my usergroup choice.
That's say, i will can do the admins first in the list, the super moderators second, the moderators third and down with.
It's will be very efficient.
Thanks!
