My name is telling it. I'm a Freehand user since a few years.
I learned the program at the graphic design school.
Later I heard from a friend who is cartographer that Freehand is a professional tool for them.

So I started to use it for fantasy maps for my Trauma Universal RPG.
You can have a look at the continental map in the german Trauma wiki:

(you have to scoll down a bit)

But I use Photoshop and real paper for cartography as well.
Have a look at it here:

I'm happy to be here, to get a good look at nice maps and illustrations.
And I hope to learn a few things.
