Afraid that you’ll miss seeing your inbox fill each day with emails from dozens of disparate student organizations and house lists after you graduate? Have no fear! A tip from a recent alum alerted FlyBy to the fact that special-interest e-mail lists exist for Harvard alumni too.

Through the Harvard Alumni Association (HAA), graduates from any Harvard school can join groups to match their interests, such as the “HAA Beer and Brewing Club,” whose members talk about that hobby; “About Sex Organs,” which bills itself as a “discussion of human sex organs, including, among other matters, their proper care and treatment;” and “Near Death Experiences Studies,” for those who have endured such crises or want to learn more about them.

HAA discussion groups have been formed to unite alumni living in various regions of the country, those who graduated in the same year, and those who work in certain professional industries.

The largest group, with 1860 members, is a networking forum called “Harvard Career,” while some groups – such as the Class of 1946 list and a group that offers singles ages 25-35 the opportunity to “make friends from all over the world” – consist of just one member.
