Thank you for your fast reply Jeff.
I have a custom theme for profile, and I've added "MySettings.ascx" to my profile templates.
I cannot find the "Add: Enabled" that you mentioned.
If vanity URL's is enabled and set to automatic, can I just comment this code out.. the entire text box on the MySettings template?
I guess I haven't grasped the vanity name for profiles and how it works.
Thank you again.
