I would like to send a group iMessage every mintue. I would like the group iMessage to be automated so I can start it and then let it do its thing. It is for a text message scavenger scavenger hunt. I have a spread sheet of 150 things that the teams need to go take pictures of. I want to automate the process of sending out text messages (iMessages) with my iMac. Help me please. It is for a non-profit event.
