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…

No problem, see pull request #4538 Thanks for using up your free tier helping me, hopefully now I can give back in thanks to the community.

Okay thanks, this is more clear now. However, I cannot find a comparable guardian method for can_change_timestamp so how do I implement that?
