Thanks -- I think I know what's going on. I've done sufficient ajax to know what's going on. However, what I don't understand is:

1. Detecting who is currently online (i.e., all who are connected to THE server);

2. And then how to send all of them stuff.

For example, if you have four people connected to the server at the same time and one sends something, then how do you forward that to each person so that their screen refreshes accordingly?
