“Ping” is the alert to call people on the list to a thread. As you can see I generally don’t use the term but instead post a comment to everyone on the list. In the case of the Beck TV thread its just a means of announcing that the thread has been posted and is active.
When someone posts “Ping” they’re simply calling others who asked to be “Pinged” to a thread.
Thanks, and I really appreciate the way you do it!
