I have updated the Chat plugins and there are some small changes to it. First of all we have a way cooler IRC chat plugin now that relays colors and all other information just as you would be chatting in-game to the IRC. Also, if people login to IRC and type there, all their status information is displayed in the game just as if they are in the game except a [IRC] tag in the end instead of the world.
Regarding the ingame-chat, there might be some small changes. Please use /ch help for details.
