Note that one common mistake that newcomers to IRC do is to private-message a user that helps them (using the /msg command) instead of keeping the discussion on the [IRC] channel.
Should it be “on the channel” or “in the channel”?
In case you are not familiar with IRC (Internet Relay Chat), then the longer story is that the chat rooms on the various IRC networks are called “channels” in the IRC parlance, and one can speak on (in?) them. Thing is "keep the discussion on the chat-room" sounds weird to me, and "keep the discussion in the chat room" sounds better. I've usually always said "on the channel" when chatting on IRC and so far no one complained, but a commentator on the text in question said he thought it should be "in the channel".
I'm not a native speaker of English, so insights would be welcome.
