Username Character Restriction

I am wanting to restrict the characters that can be used in a username when people register on the site. I have registration integration turned on so registration is handled by Membership Pro, however I can't seem to find anywhere to set the character restrictions.

Hi Chris

At the moment, we don't have username restriction (as in Joomla, there is no restriction to username like username length or characters set...)

So at the moment, if you really want to restrict access to username, you will need to edit code. The file you need to edit is components/com_osmembership/controller/validator.php , method validate_username

I will also try to support some kind of restrictions to username in the next release of the extension
