use in this format:

[a-zA-Z_0-9\- ]

How can I prevent ppl signing up with - and _ at the beginning/end of their usernames, so that they're valid for email addresses (ie. username@mydomain.com)

Thanks!

Glad someone else got some use out of this mod. I thought I was the only one using it.

Maybe it should be released..

how come i can't find any of those code under register.php

you brought up an old thread .... check the date :D
