So you've installed GIMP, you know how to work with the program, and you know a little about layers, filters, and effects. You've found and gone through some tutorials you found on the web and have created a bunch of "test" graphics to make use of some of the more common GIMP capabilities. You want to learn more. You have an itch that The GIMP Documentation pages just won't scratch.
You really want to know, what can all these tools be used for? What neat and useful things can they do? Maybe you've considered buying a book, but found them to be inadequate. You could keep finding tutorials, but those are starting to get tedious and repetitive. Besides, they demostrate capabilities from the opposite direction: They show you the end result and what tools to use get you there.
Now what?
What you want is a one-stop guide to the cool GIMP features without a lot of beginner fluff. You want a GIMP reference showing you what a capability does and some of the interesting ways it can be used.
