I've seen the word 'superping' be used across SE meta sites.
What does it mean? Is it just a synonym of the word 'ping' (ie. using
@ followed by a user's name to give them a notification in their inbox).
Superpings are a chatroom feature only available to diamond moderators, where they can reach a user irrespective of past interaction.
Compare that to a normal ping, where you can
@name someone in comments or in a chatroom only if they have been active on a post or in that chatroom.
Superpings have a specific format:
@@<site-userid>@<sitename>.stackexchange.com (the latter includes creating a chat account for the user if there isn't one yet); the message is then added to the user inbox with a link to the chatroom.
The chatroom UI for this is quite helpful in that moderators are given just-in-time help when you type
@@, and it supports searching for users by username and by site profile link. (Note that searching for users by username is not supported if the user does not have a chat profile.)
