OK. Finally, you're very lucky. I did have more time this night than I originally thought, so I can post the tutorial right now.

But since it's pretty long, and with a lot of pictures, I won't post it here. I made a webpage with it.

Here the tutorial:

Enjoy!
Tell me if you want to know more. I just covered the basics. I hadn't explained all the possibilties of WMM, far from it. But you'll know enough yet to do a good job.
