My girlfriend has a Cricut and is looking for a website that would have good ideas and tips. Is there a site that is head and shoulders above the rest?

I guess it depends what your girlfriend wants to create with the cricut machine.

The Provocraft site is a good place to start. It actually has a Cricut site and forum here:

There are heaps of videos about how to use the Cricut too:
