> What is super-pinging? How do I use it?
> As a moderator, you can send a message to anyone on the network in chat with the use of a super-ping. This message will appear in the user's inbox, even if they've never been to chat.
> To use it, begin by typing @@ in a chat room; you'll get a dialog that'll let you search for the user. Alternatively, if you already know the user's ID, you can type @@<ID>@<sitename>.stackexchange.com to super ping them.
> A user's ID can be found by navigating to their profile, looking at the profile's URL, and noting the number that appears after /users/
