Would you reccomend that I use the built in Forms authentication, or my own
design?

Basically, I need to restrict access based on the PAGE that a user is trying
to view. Some pages are for all users, some for registered users, and some
for admins. There is a login form on every page (while the user is not
logged in) and I store a session variable for username. The session on_end
clears the username session, therefore logging them out. I have a base class
that has a restrict access sub and checks that with their username and
usertype on each page. Is there anything wrong with this?
