The current site is down but the old site seems to be working so here are a few of our approved activities: http://activities.focallocal.org/
Users can suggest new one and we all discuss them and follow a process before adding them to the list (note activities and projects are different in our ecosystem).
The task for each will be to find peer-reviewed academia which supports (or argues against) the individual and community benefits of each activity. We are often met with ‘its just a bunch of hippies’, it’s your role to lay out the science behind why these light and fun activities are grounded and can make our world a happier, friendlier, healthier and safer place to live.
