I fuxking love D&D. I'm currently going through two year withdrawal at this point and I'm itching to game again. Devac is also big into gaming.
As for DMing? The first few games are hard for any DM. If I were to give one key of advice, it'd be to know your world and NPCs enough that improving situations are a cinch. That, and keep your player group small. Three is perfect. :)
