I've played all kinds of tabletop games, but Dungeons & Dragons has always been my favorite.
I've been part of a gaming group for the last 17 years; we meet every weekend for a 7-hour session. (We're kind of hardcore.) So we can keep track of what we're playing and where we're meeting, I keep the calendar to the right for our local group.
For our not-so-local players, I like to post the maps and tools I've created over the years. They're free to use for your games—just don't be going around selling them!
