I would like to allow regular users to trigger certain events (create annotation, likes, votes) on a given topic whereby the topic timestamp is updated. I noticed that the POST /t/:topic_id/change-timestamp request returns a 403 (Forbidden) whereas if I am logged in as admin it works just fine. Wh…
