I'm reworking a couple of my lists, and adding *pingfile* keywords for a couple of them. I'll post here and/or FReepmail you with updates/changes, mostly in the military category, I reckon.
Have you set a usual/common time, [quarterly, monthly, whatever for info updates? It would seem it needs to be an annual event at the very least, and probably a bit more frequent than that.
Yes please keep me updated on any changes you have. I expect to have the Master ready for publication very soon. I originally intended to publish the Master Ping List quarterly, but the Great Exodus threw everything into chaos, as we lost several list keepers and I had trouble keeping track.
