Ciao Mauro!

@You : "...p.s. forgive me Marco,is not my intention to overwrite you...scusa :)..."

One of the things I much prefer of Moi's forum is the freedom and the joy witch which its users (we) help each other with their passion.
So, you have not "overwritten" nothing :)

Very interesting your example. Almost the same I wanted to post.
Now I'm going to make a little video tut for this new user, with a slightly different approach.

Thanks and ....Ciao!

Marco (mkdm)
