Disallow username spaces

[gldtn]

Is there a way to disallow username space on registration?

You can do that in Options -> User Registration: User Name Match Regular Expression

Try using this ^[^\s]+$

How about not allowing numbers, only letter A-Z

This is from Google so I can't vouch for it: /^[a-zA-Z][\sa-zA-Z]*$/

Regex is all a bit voodoo to me

That reminds me of the Jeff Atwood thought: Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems.
