From a little experimenting I did with some of the features of this board a while back, I figured out enough to know that the s variable is a session variable. What happens is when you first log in, a random session variable is generated(long enough to ensure that it's unique) and then that session variable is recorded, along with your user name and password. So, whenever the scripts see that session ID come back to them, they can look it up within the session database and match it to your user name. There may be a way to get the chat to read the session DB, but unfortunately, it's not quite as simple as just decoding the contents of the ID itself.
