Hi Mike,
yes, I have loads of experience with the program (it's what I used for about 3/4 of a year before I could afford Photoshop 7) it's powerfull program, and there's a ton of stuff you can do with it. It's got a lot of photoshop's features, but its not so easy to navigate, and it's lacking some things (plus it's tablet support isn't very good). if you have any specific questions you want to know about it, just ask and I'll do my best to answer them for you.
