Fill out this Google Form in order to register a group with the map & directory.
Each group can only have one pin on the map---even if you have multiple manifestations of the group through different online mechanisms (e.g. a secret Facebook group, fronted by a public Facebook group or a Meetup.com group).
You will be asked a series of questions about your group---things like the name of your group; where you want your group's pin to be on the map; the URL of your group's web presence. If you have multiple online manifestations for your group, you'll be able to give information about each one. If your group is a secret Facebook group you'll be asked to provide a contact method for people to find out how to join it, etc.
You'll also be asked to select from a list of tags the ones that best characterize your group, which will help potential new members identify if your group will be a place where they feel welcome.
