art rage is a superb peice of kit, its low on cpu for the most part too, and its just a joy to sketch with. its not like photoshop though so dont expect all singing all dancing photo retouching and all the adobe magic. but as a paint program its great, esp for the cash... cheap as chips.
there are some tutorials on the artrage website here http://www.artrage.com/ infact there are some linked form the hoime page. there is also a vibrant forum with very open users discussing techniques and exchanging ideas.
I use it alot for figure studies, I work alot in watercolours but do most of my initial sketching for pose and composition in artrage. if you check out nicks sketchbook thread you will find loads fo fantastic work created in artrage, have a look see here http://community.imaginefx.com/forums/thread/10111.aspx
