If you hang out in Second Life, there are several Doctor Who events you should be aware of. Coming up this Sunday, at 1PM SL time, the Sci-fi & Fantasy Portal on Info Island will have a Doctor Who Discussion. The link to get there can be found here. The folks at Gallifreyan Embassy and Podshock also have meet-ups inworld periodically; do a search for Podshock, and again for Doctor Who. They had a really nice Tardis HUD that is fun to teleport with.
