Registered users

Hi!

I want to creat an user database in my site. I want them to register, set up a profile, have an avatar… That’s ok. BUT, I don’t want to see the dashboard AND the admin login page.

I want to put the login and password fields in my HEADER and, if the user is just a subscriber, he goes to a profile page, with a theme and this kind of stuff, not the admin panel.

Is that possible?! How can I do that?!
Thanx!
