Chugger of SCUSA boards started this and I just got wind of it. It is a map of all the TA around the world.

Per his instructions:

It's just a classic push pin map. Right now, I'm probably the only one on there, but in the spirit of the TA, anybody* can contribute to it.

[HOW TO ADD YOURSELF]
Just go to the URL, (log in with your google/gmail account if you aren't already), click edit, click on the push pin icon, drag it to where you live, write something, click save, and you're done. Otherwise, no rules, use your name, username, or whatever. You can put images in the comments too if you want with some basic HTML.
