I just heard about Wiggio (http://wiggio.com/), a program that allows you to connect with groups in a number of ways. It sounds helpful for ministry teams. Youth Leaders or Sunday School coordinators could use it to send text messages to teachers/leaders, poll them about possible dates for upcoming events, etc.
Here's their intro video:
Has anyone out there used it? What feedback can you offer? I've used Google groups in a similar way, but it doesn't have the text messages or voice messages feature. But Wiggio is free, so I wonder if it's too good to be true?
