not allowing registration with only NUMBER

[goorgoor]

hi,

i see that many ppl uses only numbers when they register on my forum! how can i NOT allow them to do that. i don't want ppl to register with only numbers like 1234 on my forum! is there any mods for that?

thanks

AdminCP -> vBulletin Options -> User Registration Options -> Username Regular Expression

See the admin help for examples.
