I think if you look at some of the GCers, especially those that post or are Moderators, many are Alums.
We all get into the world of getting a new job, or starting a Family.
Such Great posters as DAlum, Lenoxx, lifesaver, GPhiBeta Lt.Coln, JMOM, LXAAlum, ErikConard, Jono, And Many more to large to list all are Alums who maybe for some reason such as my self, stepped back for a while, but are back big time!
We are the ones who say: Fraternity/Soroity are for Life!
If it were not for the Alums of My Chapter, we would not have maybe 20 Brothers who drive to the Chapter for a Leadership Weekend, or donate money for a new House that we are trying to build, go down for Founders Day ( I worked and got 80 Alums back), or Homecominng!
Who of Greek Life wouold go back to Homecoming unless your Org. Was There?
