Hello, everybody. I've been doing FRPG maps with MS Paint for several years (and hand-drawn ones since I was a wee lad). Just getting involved in a collaborative module creation project over at Myth-Weavers, and trying to elevate my technical skills (and master a better mapping software).

Since I'm currently on a limited budget, I'm definitely interested in hearing people's opinions on what the best free mapping software is--with an optimal mix of user-friendliness, capabilities, and professional-looking product.
