Users level 5 and above now have access to the Create Room feature. This allows you to create a new room similar to rooms that already exist within everything.

A new, related macro is the chatterbox /invite command: "/invite jessicapierce" will send a message to JP asking her to join whatever room you are in. She can visit the room node to enter. Don't be surprised if she doesn't always join you though - She always has an excuse.

Have fun!

PS. You can tell what rooms people are in through the Everything Finger -- no rooms are exclusive. Also, rooms will expire a while after everyone leaves.
