https://ip.ip.ip.ip:porthttps://hostname:port
A few people have asked how to see messages and chat from when they are offline or when Colloquy quits in background(pfffft lame, it should stay online, imo), THIS IS IT. Set up a znc bnc, and it can save the buffer from chat, because your bnc stays connected to IRC, even when you are not connected to your znc
