The discussion revolves around ChauNguyen who is experiencing a recurring issue of losing admin rights to their community. itsbhanusharma suggests that another admin might be removing ChauNguyen from the admin board and recommends verifying the logs to identify the person responsible.
That is a ‘new user notice’, which is visible to TL2 users and above here on Meta. It’s something to encourage a friendly welcome and a slightly more relaxed approach to anyone not quite getting the hang of everything straight away.
I don’t think it has anything to do with the disappearing admin issue in the OP though.
