I just discovered a site that not only has instructions for how to use the GIMP Tools and what they are used for, but also there are videos at the top of each article that explains more in detail how to use these tools. Now I admit, it seems that the tutorials this man gives are from a previous version because the set up does not look like the newer version that I have, but the tools still work the same way--just in a different place. Here is the link for anyone who is having a hard time learning GIMP:

Hope it helps you as much as it has for me!
