Any way to ban pseudonyms?

[Allen Brown]

Is there a way to make sure that someone's username is their real name? So instead of registering as jackass23, I'd have to register as "Jack Hass" - assuming my name was actually Jack Hass of course

I know this isn't the way forums usually are but we have a rather "businesslike" application where it's more appropriate for people to use their real names.

I know I can reject people and make them register again but I'd rather try to force it (or at least strongly suggest it) on the registration page.

Thanks
Allen
