I have created Banner-exchange of my own if you like to share it for others. I'm a 1994 UT IE graduate. Anyways, I like your site. I was looking for e-mail addresses for the UT IE professors, and stumbled across your link. Chatters actually can see each other.
Users can alter their look in the chat, construct their own chat-rooms and invite guests.
They also have FREE email and FriendFinder. You assume all risks associated with the using theGuestbook.
