When I first saw the Profile Manager module I thought that it was a great way to view your information all in one spot. Instead of having to go into the Administrators module and sort through all the users to find your information, you can just click on Your Profile and see your User Name, Email and all of your modules in one easy place.
My favourite thing about this module:
I really like that it is a general overview of just your information. No need to wade through other users.
