Okay, so I just got Adobe Photoshop CS as a 30 day trial or so.. actually, there's probably only 13 or so days left now. Anyways, I wanted to know some tips on how to use it, because so far I have basically no clue on what I'm doing. I can pretty much retrieve pictures.. that's about it.

Any tips?

Especially for animation, I'd like to learn how to use this.. before I go out and possibly buy it.

Or are photoshops 6 and 7 better?
