We had the same problem before when we first started trying to get chat night up and running- I think it might be best to cater to all tastes.
So that the person who doesn't like "cybering" can sit in a chat room alone?
Actually last time we tried to set up chat there were quite a few people who resisted the sex talk, but I'd put money on which room will be the busiest (or at least the most fun).
I do not object to whatever other people want to do, but I did object when Hiro repeatedly asked me to talk dirty to him. I think it has to be up to the individual chatter, whatever they want to do.
Sorry I missed most of the chat. I was in and out, but my computer crashed half way through.
