Whenever I try to add someone to my notify list (or remove them), using the commands for the editbox, this always appears in my status window:
-----THERANDOMDOG Unknown command
(The -'s are there for other purposes, that is not what appeared.) Obviously by my username, that is my nick. It always appear when I type in /notify [optional commands]. Even weirder still, that wasn't my current nick, so I don't know where it got that.
