The idea is simple.
If the user is singed-in, the frontpage will display the profile page.
Any clues about how I can go about this?
I tried adding
theme('user_profile',$variables = array($account => $user)); in the php snippets.
This gave me a warning when I saved the configuration:
warning: uasort() [function.uasort]: The argument should be an array in user.pages.inc
