We are here to have fun. Forum names can be anything reasonable. Pick one that is appropriate for you and your personality -- perhaps a game character or a non-player character or a super-hero or a super-villain.
Duplicate names are not allowed. Not even close duplicates will be allowed. Use your creativity
Under no circumstances should you try and pick a name that is offensive, profane or otherwise inappropriate. I have all the final say on names, and I won't play games about this. We will have kids of all ages on this site, and names that would be offensive, profane or otherwise inappropriate for kids are inappropriate here -- period!
That should be enough said.
