This is not an actual hack request, but a question!

I've seen many good hacks, and ive seen worse, but i've never seen a "ban by username" hack, some of my friends asked me if i knew if that was able to get, but i dont know why they didnt ask here... thats why im asking if there is a "ban by username" hac out there?

Actually... looking at 2.03 - in the admin CP - under the top options --> change options -->User and registration options --> Illegal user names :

Enter names in here that you do not want people to register. If any of the names here are included within the username, the user will told that there is an error. Separate names by spaces.

Is this not what your looking for? Don't think a hack is requird for what you want here. Hope this helps. Let me know if this is what you were looking for or I'm just confused.

oh... didnt know that, thanks!

No problem. Anytime I can help :D
