I am just a total noob at map making, I have installed GIMP but I am still figuring out how to use it (the price was right). I also have CC3 that I recently found the disks for that I am toying with. I have a 6 month old so finding time to learn new software is somewhat of a challenge.
Welcome to the Guild AClark. There are some good tutorials here that can walk you through the steps of map creation in either program. Check out the "Tutorials in PDF Format" thread for more. Best of luck man.
