20176	Allowing the Developer Filter the Regex on wpmu_validate_user_signup()	webord		"So I've been having a problem with the way WordPress Multisite handles the restriction for new users. 

Looking at the file ''ms-functions.php'', I saw no Filter to the regular expression applied on the user_name to do it's validation. 

I've changed like this, so by default you will be restricted to the ''[a-z0-9]'' pattern, but if needed the developer should have the power to filter that. 

This might need a patch for the domains."	enhancement	new	normal	Awaiting Review	Multisite	3.4	normal		dev-feedback	webord.net@…
