Roughly 10 years of experience playing DnD 3.0/3.5. I've spent a goodly portion of that DM'ing, though I prefer to be a player. My pnp group has experimented with a few other systems; 4e dnd, and pathfinder specifically. I enjoy both, though I do have a preference for Pathfinder given the flexibility of the system.
Feel free to send along a PM if you have any questions.
