When Admin is Offline

Hi, I posted to the website but my post disappeared. Thank you for this plugin! I don’t want people chatting without a moderator or admin present. Is it possible to either:

automatically display a notice saying the admin/service is offline
completely close the chatroom when I go offline

I hope there is a simple solution that I have overlooked ??
