It's interesting to look at your neighbors on the net when you have your own domain name. Obviously, I have "JERF.ORG", which you think would be kinda isolated, but that's not true.
I receive a lot of messages directed to INFO\@IERF.ORG. (All caps deliberate; I get stuff from IERF precisely because j's look like i's.) IERF seems to be a teacher re-certification group; if you have a foriegn country certification for teaching, and would like to translate that into a USA certification, they're the ones you talk to.
A new one I just received a message for is JDRF.org, which is the "Juvenile Diabetes Reasearch Foundation". The Internet makes for strange neighbors.
