A ping list is just the screen names of those you wish to “ping” or alert to a certain thread, separated by semi-colons.

It is considered impolite to put individuals on a ping list without their permission (ie. sorta like spam).

I'd be willing to hold the ping-list of the ping-list of the ping-list. And if there isn't such a thing, there should.
