Oh! The RKBA (Right to Keep and Bear Arms) ping, I believe is done by Delta 21.
I thought that Mark Twain did the RKBA ping list. I am pulling backup on the RoadKllBeeberAsociation(also RKBA) /VK/ZOT list and have been primary on the TREADHEAD ping list for all things encased in heavy armor and propelled by tracks.
I know with the epic failure of the Soviet Bear in its attempts to capture Ukraine, there is an overwhelming need for TREADHEAD threads. Your enthusiasm with the ZOT list is inspiring to say the least!
