[spit_f1re88]

I've been having problems with members that has wierdo names and has many symbols. I found this mod in vbulletin.org but i can't find it here so.

Restrict usernames to alphanumeric and underscore - vBulletin.org Forum

Do you really need the mod?

This is already possible in default vBulletin, since 3.6.8 if not sooner.

Admin CP -> vBulletin Options -> vBulletin Options -> User Registration Options -> Username Regular Expression

Wow.. so quick..... Thank a LOT....

O god ... there's no option to set the minimum/max length of the username......

Btw shld I remove the values STored in Regular expression box in vbulletin options to make this hack work?

I am using ^([a-z]|_([a-z0-9]|$))([a-z0-9]|_([a-z0-9]|$))*$ as my regular expression which is working very fine BUT I want to make it to check for minimum length of 5 chars and maximum for 15 chars.....
Plz help me modify this regular expression..... I know that there is smthng like {4,15} to be used but dont know how and where...... searched throu net but no luck...
