Welcome to the Guild Don! Well you are here for the same reason that many people joined up. The good news is there are allot of resources within the tutorials section to help you on your way. I myself have not gone the Campaign Cartographer route, though there are some members of the Guild here that do good work with it. If you already own Photoshop CS, then you will be able to use the tutorials here to create some really fantastic maps, without needing to purchase any additional software. If you do not own PS, you can download GIMP, a raster program with many of the same features as PS, for free. I have been using GIMP for the last three years and, while I do intend to upgrade to PS eventually, have found it adequate form most of my mapping needs. There are also quite a few tutorials written for GIMP users here as well, though sadly, no town/city tutorials (though much, but not all, of PS tutorials on this topic can be translated into GIMP). I wish you all the best, and feel free to ask any questions you may have.
