I've noticed that there isn't a tab to log you out of it. After I closed that page then tried to re-logon, it told me that there was already a wildcard so I had to wait until the session timed out to be able to again enter chat as wildcard. Without the chat automatically using your official foosball.com login name, and then having a way to log out of it when you are done, it seems ripe for abuse by anonymous posters.
