The chatbox has been removed due to a compromise in the system.
There was a way to access the commands, and now that it's been taken advantage of, it needs to be removed temporarily to be fixed.
The chatbox will be back as soon as possible. Just check back for it.
If you'd like
Tinychat.com/pspmod will function as a temporary replacement for the chatroom.
This will be the "official" chatroom until further notice.
