Finally Through all of the Material Covered in the 2008 Version

I am currently on lesson 5 as I post this.  I work slow, huh? Sorry.  In my defense this is all new to me. Photoshop was new to me when I got to college.  Tiny town Missouri doesn't typically invest in computer programs, or art programs for that matter.
I made a tunnel in a box and was happy to see that one of the new curve functions was the same as the ones in Adobe.  I haven't taken a screen shot of every lesson, so as to save some space, but I have watched them and learned what they are discussing.
