Ahhh neat, @rra and others are running a workshop May 13-14 to help existing communities get onto Hometown. Looks like the prerequisite is to set up an instance (either self hosted or just purchased via a host like @support). Then the workshop is going to focus on the *social* aspects of running a small community and how to keep it lively and sustainable. Cool stuff!!
