Would you except a patch to this module that would make it possible to exclude the username and/or password from the email that is sent out. We are using the Email Registration module(http://drupal.org/project/email_registration) so do not need the username in the email (in fact Email Registration creates a random string for it so it looks bad). I was thinking of having two check boxes on the ucreate settings page. If you are happy for this to be added to the module I will create a patch with the code change.
