When you "ping" someone on a thread, they'll get the message, "New Messages for You" on the main screen, and the message will appear on the "My Comments" page.
A "ping list" is something one person keeps of people that he/she knows are interested in a particular topic (either broad or narrow). If I had, say, a Brooklyn ping list, and someone posted an article about Brooklyn and I saw it, I would ping everyone on the list. I would want to let everyone know that it's there because in an hour, that thread will be buried under a stack of newer articles and they might not have seen it.
Anyway, if you want to be on anyone's ping list, ask anyone that you see pinging a bunch of people.
I have a list of names. When I start the new book thread, I will Post a Reply, but I'll erase my name and cut and paste all the other names. They'll be able to find the thread that much easier.
Hope this helps.

Thanks!! I wondered how that worked and your response is much appreciated.
So . . . please add me to the book club ping list.
