Username Letter

[Mum]

How can i make it that the first character of a username MUST be a letter?

[Dismounted]

/^([a-z]{1})(.*)$/i

Thank you, i put that in username regular expressions, and it will also let it be upper or lower case?

Thanks so much

Just tested this, tried *test, it didn't let it through, great, tried 1test, it didn't let it through great, tried test, and it wouldn't let it through LOL

Thanks in advance for looking into it.
