Bradley asked me to answer this, and when I see the question I am not sure if you mean the curation trail or the #IAmAliveChallenge community on Hive, but here is Bradley's post on how to join his curation trail, Joining a Curation Trail... Updated.

You can also join the #IAmAliveChallenge and out Hive community by looking into our guide, I Am Alive Challenge - The Guide.
