ClassMates.com is another HighSchoolAlumni.com-like site. They claim 2.25 million registered alumni, which I think is probably a lot more than HSA, even though there are actually less from my graduating class (though, I may have skewed that average some). It's also faster and better-done. And they just signed
a deal with Lycos, so they'll probably be doing even better, soon. On the minus side, you have to be a *paid* member ($25/2 years) to actually contact any of the people listed, which seems kinda lame -- but hey, everyone needs a business model. More or less.
