Swords never stopped the Conan the Barbarian SF fans from getting into a convention, but there likely would be advance rules regarding costumes.
Cute Dog, looks like an English Setter, we had one of those 20 years ago, lovely dog.
I agree with 2JM about beiong concerned about meeting people over the internet, look at the CGEB story, as well as the recent Commensense problem, but I would think that there would be safety in numbers. Also, I would hope that any stalkers among us would be exposed by that time. :-)
On the other hand, that's how Rose and I met. Well, pre-Internet really, but the concept was pretty much the same... and we've been together going on 13 years.
My thought is that's why we don't "open this up" to everyone. We have the regulars here and may lose some and gain quite a few more before then.
But I think we go to a more secure location. Maybe set up a Yahoo Entmoot group. And we'd only pass on the info via freepmail once we got to know someone. Then we can talk about details.
That's especially important if we end up at someone's house.
