Well, the reason I asked is that not all yeshivos are the same or may be perceived as doing things in a way that drastically need to bring them into the 21st Century, as you suggest.
Incidentally, many yeshivos do fine with the UPSP. I get alumni and dinner updates in the mail on a weekly, almost daily basis, from yeshivos I never heard of or certainly never attended.
So you want to protect us online here but improve systems to keep track of yeshiva alumni? I think they know how to get in contact with their yeshiva if they want to be kept updated. No?
