The quit menu having the ... to indicate that it will prompt is still there even when you are not connected to anything - in which case it won't prompt. Should just be "Quit Colloquy" when you are not connected. (Possibly related to #261 in that it is to do with the prompt.)
(Also a little odd that it has the ... in the first place. While it does certainly follow HIG for a menu item that prompts, I can't think of any other application that prompts that also has it on quit. It looks (I think) a little out of place. As I'm used to looking for a Quit without it, it is unexpected. On the other hand, it does provide a clue that option or shift or something might produce some other option. Ideally I'd like to see a plain "Quit Colloquy" and a "Quit Colloquy Now" or something on opt. Thought I do understand the reasoning behind having a ... if it was up to me I'd lose it.)
