Chris wants to create his online community, but he's concerned that using Facebook or Twitter will make it owned by them or shut him down. Leo says that is true but it's an easy place to start, and that's also where all the eyeballs are. Leo recommends going with Google+ because he'll get the Hangouts feature, messaging, and even Google groups.
If he really wants to do it right, it's best to make his own website with those capabilities. That way he can control it if his community gets shut down. He also wants to take donations. Leo says that SquareSpace has a great cash donation payments option.
