When do you become an alumni?

[Greg Ross]

From Dictionary.com:

Usage Note: Alumnus and alumna both come from Latin and preserve Latin plurals. Alumnus is a masculine noun whose plural is alumni, and alumna is a feminine noun whose plural is alumnae. Coeducational institutions usually use alumni for graduates of both sexes. But those who object to masculine forms in such cases may prefer the phrase alumni and alumnae or the form alumnae/i, which is the choice of many women's colleges that have begun to admit men.

So, Angela may or may not be an alumna of S.P.A.M. Erin and Randi are alumnae of their respective teams. D.J. will be an alumnus after IRI, and they will all be alumni (or alumnae/i bleah! I prefer alumni.) But if you're lazy, and still want to be at least marginally correct, you can just call them all alums.
