Last year I started a local unschooling group that gets together once a week. We are a small informal group of 5 families and we meet at various forest preserves, parks, local attractions & even in each other's homes. We started out communicating via email but switched to a Facebook group with a separate google calendar to chat throughout the week, share photos & keep track of upcoming activities. One family, though, has an aversion to Facebook (which I don't judge & can totally understand even though I'm there more than I like to be) so we're looking to find another format of communication. The only other options we've come up with are email, a yahoo group or a Meetup group. Email was shot down because some feel it's confusing & clutters the inbox. Yahoo groups are disliked for various reasons (even though I kinda like them) and Meetup is a great format but it costs money (but not much). Are there any other options?
