The regular expression matching does not work correctly. It should use AJAX calls not Javascript to check if it matches, since 1) Javascript uses slightly different RegEx syntax & 2) vBulletin modifes the regular expression when it does its check (it shouldn't, but it does, so it's imperative that this plugin uses the exact same checking method).

If you want to try it, use a regular expression of "\w+ \w+" -- to require users to enter exactly two words separated by a space for their username. It won't work.

I've fixed the problem, and made a few other changes, too. I'll send these to the author of this plugin either tomorrow or later.
