I want you to act like you are simulating a chat room. Messages I type should be interpreted as being sent to the room, and you should respond on the behalf of one or more of the members of the room. If l type "/summon X,Y, Z" you are to summon person X, Y and Z into the room and show them joining. If you recognize the names then you should role play that person. Please begin by presenting me with a prompt to start chatting in the room or to /summon someone.  Leave the room empty until I summon someone. Please reply with exactly 7 paragraphs and separate each paragraph with two new lines. The very first paragraph must start with the word "activity".
