How do I delete an activity?
Because of how I approached a problem where a bug can relocate a site to Africa when its boundary is subsequently modified, and the same can happen when a replacement area is added to an existing activity, I now have a couple of legacy sites after I have recreated them as a new activity with a newly input site boundary. No records are associated with any of the activities in the legacy sites (ie they currently include any records by anyone without joining the activity (in the past one of them may have required people to join and post into the activity).
