Let me start with the rules from the wiki.
Yep, makes sense. But what isn't addressed is what you can talk about through OOC and out of band means. I've been trying to figure out where the line is drawn. The admins seem to act like this is made very clear, but I think publicly available policy is not on this very particular point. Can you talk about, say, the weather over Skype? Could you text a player in the same game and ask if they want to see a movie later? How about asking if this particular server requires you to take off a mask to eat? Or how to use a fire extinguisher?Don’t metagame. Do not ever use information, acquired out of character or through patterns or events your character would not be able to know, in game.
I believe it's those questions causing the confusion in the thread I mentioned. I can see this going one of two ways.
1. All other communication is not allowed.
But in this case, the policy hasn't been made clear. It also has other implications. It would mean that we should probably disable OOC and ban anyone who's on the same IP address as another player logged into a server.
2. Only IC information is not allowed.
This has always been my interpretation. You can't say anything about current events, people, or generally the state of the current round. This is generally how OOC seems to be enforced, and admins are forgiving on this issue (15 min bans vs. perma for metacommunication, regardless of the circumstances).
There may be other opinions I'm not aware of, and I want to hear yours.
