A few weeks ago I stumbled upon this site while searching for ways to make some maps I needed for a campaign I'm intending to run.
In the mean time I did start these maps. They're not that good yet, but I'm learning.
Finally decided to also register myself here.
Welcome to the Guild, The Mappiest Place on the Web :D
If you want to improve your map and mapping skills I strongly suggest that you post up a WIP )Work In Progress) thread because you will receive all sorts of guidance through comments and critiques that help you on your way.
