well, I must say that you found the right place for help learning mapping with ANY sort of software. Post your work as you go and people around here will have you making maps that you never would have thought you could do.
The software forum is the place to discuss the various progs, and the Tuts or how to forum is where you will find all kinds of pointers. but nothing beats posting a starting work-in-progress in the appropriate WIP forum to really learn.
As has been said many, many times around here....
"post maps early, post maps often, but POST your maps!
