I tried three of your tutorials yesterday... two after I wrote the message above. All of them were continent-type tutorials... under the assumption that I would learn more and understand better. I have learned quite a bit, although clearly not yet enough.

The first thing I learned is: don't start with a large continent as it makes everything that follows harder.

When I get to the point where I know enough to ask an intelligent question, I will ask it. At present I'm not there yet. Thanks for trying to help though.
