Richard found this one for me. It has "lessons" for you to practice with. If you look on the far left column you will see Learning Center. Click on that and you will find all the lessons.

This is the particular less I did yesterday to get me started to make my two siggies above. It's on the site above and teaches you to combine pictures. It's the only lesson I have done so far.

Hope this helps everyone, it did me.
