ADMINS: Beware fakes. Don't trust that anyone else is an admin unless they can use !run_other successfully to make you say something (!run_other|pw|who|say|test).
NEVER pm the password.
I've added more authentication to the admin username system for now, but it won't stop anyone.
As an alternative, the web chat is operational, and can be found here: https://django-chatroom--pyelias.repl.co/
It is much more secure.
