Prevent Email Address as Usernames

[hbalagh1]

Anyone know how i can prevent my users from using their email address as their username. Personally I don't know why anyone would want to do that. Specially when their email address consist of their first and last name.

Thanks in advance

Put @ in the unallowed characters for usernames in your vBulletin Options.
