I can't seem to figure out how to stop joining the same channels everytime I connect, either when opening program for the first time or reconnecting. I have nothing in my perform list and everything relating to rejoining under IRC options is unchecked. I want to stop joining this one channel because no one uses it anymore and it's pointless to be there.
You may have a script that is joining channels, or the network itself is forcing you into a specific channel. If the network forces you into a channel, there's nothing you can do about it. If it's a script, you just need to find out what script.
