Firstly thank you for your plugin!
I tested it and it allows me to solve a problem after I upgraded to WPMU 2.9.2 to WP 3.0.1 (Mulitisite) : provide an opportunity for a blog admin to edit the user profile of other users of the blog.
Your plugin gives me this opportunity and even more ...
However, it also something that seems to me dangerous : allow an admin to switch to the profile of a superadmin if he is declared User Blog!
Is this normal and wanted? And would you have a solution to prevent it?
Thank you in advance for your reply
