There are now global and local channels, one for in-character and one for out-of-character conversation. Global speaks to everyone on the server, while local only send whatever you type to people nearby.
You switch between them with the /ch [channel letter] command, channel letter being either "g" or "l," depending on which you want to be in.
Anyone ELSE who asks about channel chat, I'm directing to this post.
Matt, I realize it's obvious, but not everyone catches everything that's right under their noses. Try to explain things a bit more, if you'd please. At the VERY least explain what you're doing to ME and I'll spread the word on the forums of what's going on like Bonn-o-Tron.
