I'm interested in getting information on where to start with Fitnesse. I've been using automated performance tools and regression tools (Silk, Mercury, Selenium) but I'd like to start learning more about fitnesse but I have no idea where to start.

I'm working on web page project right now and would like to get an idea how I could, if possible test the web app (from behind the scenes) using fitnesse... if that's how I should be using it.

I've seen the calculator example on the fitnesse site, but again can I implement fitnesse into testing a web page. For example is there a way I could test functionality of ticketmaster.com? Users creating accounts, navigating, buying tickets and logging out. The creating accounts (info sent to a database), the purchasing of tickets would be what I needed tested.
