Replying to my own post. If you do decide to go with graphical user levels, don't forget to create an "administrator.gif" graphic. Also, if you've manually added user titles to specific user profiles, you'll need likewise named graphics.
I gave it a whirl on my web site and I think I'm going to switch back to text based user levels. The effect wasn't bad, but I made the mistake of making "fancy" graphic for the admin...and the users didn't like their little stars in comparison
Thanks for all your suggestions on graphical user levels. What I'm going to do now is see about getting the Avatars up and running. If I recall a recent thread, all that was lacking was a user upload feature?
