Wsup everyone, i got a board going and i have members signing up using non-alpha characters... for example i had someone sign up using *Dazed* how can i set the board to not allow characters such as *'s on the board?

when they signup use a regular expression to validate like:

regex = "[a-zA-Z]*"

this will only match for characters A-Z both upper and lower case. If there isn't a match then the username is wrong.
