A run club, a bar, a library, a climbing gym, a parks department — anywhere people already gather. Post what you have on, and reach the people nearby who are looking for something to do.
Not open yet. Organizations are being added by hand while we're in private testing. If you run a place or a group and want to be one of the first, email matchsetgo@gmail.com and tell us what you do.
MatchSetGo is a town square for activity invitations: people post what they want to do, when they're free and roughly where, and someone else says yes. Organizations are how a neighbourhood's real places show up in that square.
