Happy New Year to anyone who is still reading this forum.
Sorry that after some very interesting discussions here earlier in 2010, things tailed off towards the end. My fault for not putting in more time to build things up, I'm afraid. Sorry too for the spam invasion that has occurred over the last week while I've been away at a philosophy conference. For the time being I've switched things so that new membership registrations need admin approval. This is not ideal, but its the best I can do for now. I'll try to get things sorted out next week, though I'm very short of time.
Anyway, I hope all space enthusiasts have a very happy 2011.
