GGG -- "Gods, graves, glyphs" -- it's a ping list for various historical and archaeological threads.
SunkenCiv is the manager of the ping list, and is doing an excellent job. If you are interested, you can send him FReepmail.
You have a choice of being on the "regular" ping list, being pinged to every article, and sometimes there are quite a few, but all interesting -- or if you would rather not get so many pings, he also puts out a weekly digest, which has links to all the week's threads and some additional ones, and you get that once a week.
On a regular ping list, you get all the articles AND the weekly digest ping.
It's a ping list that has been around for some four years, and has over 500 members and growing.
"Subscription" is free, so you can try it, and if its too much, you can always switch to the digest or cancel it alltogether.
But there are many good articles I would miss, if I wouldn't get pinged to them.
When we post or see articles posted that fit the "GGG" topic, we ping SunkenCiv, so he can ping his ping list.
Three guesses as to who started the GGG ping list.
