WARNING: The information on this page is seriously out of date. You'll most likely have better luck using World Alumni Net, or another similar service, to keep track of DHS alumni.
If you're a Downingtown High School alumni, there's a mailing list you might be interested in -- send mail to notdhs (at) mit (dot) edu to introduce yourself, and if you want, someone will add you to the list. The only "requirements" are that you're a DHS alum :-). However, in the past, there have been several people who've wanted off the list within a few days, as most of the traffic on the list is idle gossip, flaming, and the such, amongst my high school friends.
