As far as queries go I think they would be the same. I know originally that add-on had problems not displaying a users avatar if they had not uploaded one. This one does display all correctly.
You should be able to overwrite that in the EXTRA.css, or TMS. I hope we can update this sometime when time permits for ragtek. I was working on a style property for the addition of the avatar so it can be styled easily for many different styles.
I had the same problem.. Never did install it because i couldnt extract the zip.. Actually that was a few weeks ago and i forget the specific problem but it was zip related.
