Yes, registration options in the ACP i believe.

I'd ban all non-regular characters. But it's up to you

[Cryo]

Admin CP -> vB Options -> User Registration Options

Under Username Regular Expression add the following.

^[A-Z0-9 ]+$

This will restrict the username to letters, numbers and spaces only.
