JGroupChat is a simple plugin where you can create a group chat and still have access to the main chat. With your chat created, you can invite players and send a message to players in the chat with the command '/c [message]' and still have access to the main chat, and new to JGroupChat 4.0, if you use '/Jgc Toggle' your chat line without '/c' will be sent to your group chat, although you will loose the ability to send main chat messages, you can still see other player's main chat messages.
