Or do you mean to a personal name that you've put in yourself??? If so isnt it only admin people that can change them? I've had them do it on another site for me, dunno if they all work the same?
If you're talking about where it says newbie, and fishaholic, and other things, you have to have a certain amount of posts to change it to whatever you want. I think its somewhere around 1,200, or 1,500.
i know that. what i meant is that some people: pica_nuttalli has retired windowcleaner, teelie has That's no moon, it's a common pleco, modernhamlet has Just this guy... etc have different ones that seem more personalized than "standered" ones and i was wondering how you would change that.
