New Users (registration issue)

[Sawa Dee SohL]

How can I make it so members can only user certain characters, when creating a name?

For example: Users can create names with all the symbols - but I would like it to be limited to only a few symbols, not them all.

Should I put the characters under Illegal User Names - or is there a different way to do it?

I also had someone sign up on my site, that was a completely blank user - no information, no IP - no username (was blank) - last day they where 'active' was Dec 31, 1969 - anyone know why this happened? (2 members did this)

AdminCP - vBulletin Options - User Registration Options - Username Regular Expression and choose the settings you want.

Doesn't seem to be what I'm looking for.

I just want to make it so only 4 characters are useable: ( . ) ( - ) ( _ ) and Space

Not: ~!@#$%^&*()=-|}{|\[]?><>":";'

There are articles on how to do this.
This is an .htaccess feature, where you add a line of code into your .htaccess file

It is what you are looking for. You just need to specify a regular expression.
