Creating a new admin page

Hi guys -

I've been using Project Pier pretty religiously and love it. I recently took some Time reporting code from a forum post and have it working and everything.

The problem I'm having is creating a new page in the Administration drop down at the top for Time Management tasks. I've been able to add the link in there in the panel but when navigating to it i get an error saying that 'activeCollab' could not handle the request.

I have a pretty good working knowledge of PHP and the MVC framework - are there controllers needed for creating a new Admin page? Any help would be greatly appreciated.

Mike
