Thank you all very much for your replies!

@jt411: I've already checked Marks' tutorials, but they are all movies and, as I've stated in my first post, I'd love to work with written tutorials, it's easier for me at the moment. Most probably I'll check them out later when I'm a little bit skilled ;o)

@bwtr: thanks for that link! Besides the tutorials this seems to be a VERY interesting side, too! And you mean I can simply start with any of the tutorials? I'm sure I'll try it this evening.

@GKDantas: The link is saved in my favorites!
