@Bigdave: Where did you find the tutorials from, like what website? I found a good place for great GIMP tutorials for maybe you (since you seem to be in an advance level ><).

Oh crap, a animation of Rain tutorial *0*. I'm gonna try it out just for fun!
EDIT: I did the tutorial, and now I know how to make a gif now XD. I'm so happy now <3.
