In a way it's a good idea, but then I don't know whether a lurker or people would want to post them on a public forum.

It might be a nice idea to add the first two questions to the registration process, as voluntary fields, obviously the third is moot as they aren't really lurkers when they join, although I guess they could have been.

Me (stops drawing): No
Ella: Star Trek?
Me: Yes!
