I've tried sending test messages to every public key I've seen posted here, from my Founder ID and also from a test ID; I'll wait for any replies.
The public key of my test ID is:
6wnrX9pWu8BojZoGNVD9TzH4DM9aiAPuUDk819gQ8CUbvW8HZk
I would be curious to know whether the private key for this can be acquired and imported into anyone elses' profile, to make an impromptu test list (shared ID).
