Is it possible to have the chatbox work as IRC does where it only loads the chats that have happened after you have the page opened in your browser? Because right now everyone can see chats from say, the conversation the night before, which kind of sucks for the people who had that conversation.

Also is it possible to have the title bar of the page reflect when there is a new message?

If what I am looking for is not MGC, please point me in the right direction. Thanks.
