I would make use of the group to share info, but the link to the channel would remain the same, and I don't want to give the impression that Alex is the one posting.
Alex realized he didn't have the time to manage this platform. He attempted to delete the channel, but removed himself instead. That leaves me here as admin, but without full privileges to close the group, or add other admins.
We have both exited the chat group as well, and we can do nothing about what is posted there.
