Thread: address book--how do you make a group entry?

I can't seem to make a group entry in my address book. Each entry seems to be limited to a single name. So if under IdiotCommittee as a 'name' you put idiot-1@stupid.edu,idiot-2@stupid.edu, etc., the panel says it is not a valid address. How can I made an address that will send to a group of names? I hope this can be done without code, which is currently beyond me... Thanks!
