I have been messing around with it a little bit, and for some reason I cannot figure out where to tell the pizel size of say a marquee if im drawing it. As far as I remember, the old photoshops had a bar at the bottom of the screen, and as you drew a marquee (rectangle) it would tell the size of it. I was following a tutorial that said draw a marquee 700px by 20px and I couldnt find anything that would show me how big I was drawing it!

The Info pane tells you the Width and Height of your selection (Should be somewhere near the Navigator and Histogram panes).

But first you have to change your units to Pixels (instead of inches or CM or whatever) in edit->Preferences->Units & Rulers.

Ah, Thanks much! I was only seeing it in inches which was not helping much at all.
