I'm not familiar with "ping lists", but if you mean a list of people you want to receive notifications, just create a text file on your computer with lists of people for certain topics. Then C & P the appropriate list from the text file into relevant posts.
@PeteS in CA Why should I or anyone else do all the work involved in keeping lists,when people can sign up to be pinged to each individual subject they are interested in reading and posting to by simply signing up for "Impeachment",for example?
Or elections,duck hunting,book reviews,food reviews,local elections,national elections,medicine,and any other subject in the known universe,including a ping list for the known universe?
If you sign up for one,you can also remove yourself from that ping list if you change your mind. You don't need approval from anyone to become a member of a ping list,and you don't need to get anyone to remove you from a ping list.
Frankly,I am bewildered that I am still having to ask for this after all this time.
