So I'm going to learn Jazz now, I've really been getting into, it's great.

I'm learning through one of the lessons onhere,which seems good. And I was wondering, just to be completely sure, is the circle of fourths the same as the circle of fifths?

Also, any links to great jazz guitar sites and lessons would help, since I do understand jazz is a very big subject. Ok, thanks. :]
There are nice links to jazz things in the MT FAQ Sticky at the top of this forum.
