In my experiences with chatrooms (especially for those who are single), I met some weird people on there, so I am not too comfortable with chatting with some of them. I have met some nice ones but one cannot be too careful as you can meet some who just outright weird (I am talking about the ones on AOL chatrooms).
Same with emails....I once got an email from a guy I never heard of or even seen asking me if I want to have a baby with him, because he's about in his 50s and I was in my 20s! *coughs* I was in dating forums, trying to meet someone nice and all I got were crazy men. LOL
So it's a bad idea at times to be in a chatroom.
