I remember there was a "guide" on how to change the background(with an image) of the users' posts.

let me make an example to make it more clear =s

I want to change the background of usergroups.
usergroup#1 got 4 members all those 4 members when they make posts on forum the background will be different

well more or less the same thing as its in here the staff members got that.


anyways I remember I saw this somewhere but I cant find it now

oh well ok I will move it there sorry =P
