After over a dozen years I still haven’t picked up all the Freeperisms - what is a “Q” ping? The only thing that comes to mind is a ping to that character on Star Trek The Next Generation.
People need to be added or removed, depending upon if they want a notice or not.
Q is an unknown person who seems to be close to Trump and who posts in a different website.
A Q ping is a reference that the person who holds the collection of FReepers who want to be told about new Q news should or did use this thread as that alerting occasion to those FReepers.
I like your interpretation. I’m probably doing it wrong since this is my first Ping list. People who want to know if content related to a certain is posted, they can ask someone “add me to your ping list.” The FReeper creating the ping list maintains a list of usernames of persons interested in a topic they post on. So when I saw this information I posted it an then sent it to a preformatted list of users so they’d know it was here. :)
This thread (https://www.freerepublic.com/focus/f-chat/3623181/posts) does a good job of explaining who Q is, and why there is a ping list.
