How i Change Users Posts and Threads Background colours look like different from others ?
I want to change administrator and moderaters posts & threads background colors .

I am not an expert on this, but this can probably be done in the postbit templates.
I remember messing around with it one day and I change the background color of threads somehow, so this is possible.
I tried doing something like this with profiles, but I messed up so I had to do a backup.
