Join a Group
You can find a group to join on the map below. Green and blue markers on the map identify existing postcard groups.
Zoom in to find groups close to you. Groups displayed in green are taking new members. You can select one of them as your postcard group - find one near you if possible. Once you have the group name, fill out this form to contact the organizer.
If you can't find a group to join, please consider starting your own group or proceed to do it on your own as an individual contributor.
