Currently there is no single point of contact, to be able to reach all the moderators. With their mutual understanding, moderators should create/rename a chat-room, which can be reached by all the users.
Since, the chatroom belongs to moderators, they can always unfreeze the room after long period of inactivity. Also they may delete the non-productive chats.
On the other side, users also responsibly should use this chat-room only for the purpose of issue-discussions, and use other chat-rooms for philosophy, chit-chatting, timepass and so on.
Objective: With this, many complaint based meta posts can be avoided.
