Oh, sorry, I misunderstood you. I thought you were saying that they might have been premium before, but they got thier posts revoked or something, sorry....I get like dyslexic when I'm tired
Err, anyway...so you were talking aobut yourself right? Well the reason your post count went down was because the Forum Insanity and New-Mebers sections no longer increase post count, so any post you made there was taken from your post count
As for getting a name change, perhaps if you ask nicely maybe an Admin will let you get a name change, but as of now you are not a premium member (The red username is only there because you used to be a premium member)
