Customizing Error Message During Registration

To do that I think you'd need to edit the file includes/class_dm_user.php, and find the occurrences of usernametaken. You could add a "translation" of the existing usernametaken to say what you want it to say when the user name is actually taken, then create a new phrase for "doesn't meet standards" and change the "usernametaken" to your new phrase variable in those cases.
