Most all new Grads go through the what me syndrom.
"I did my time and am ready to move on", But, for many, do you go back to your School for Homecoming? If so, where do you go when you get to College Town USA? The Chapter House which is the focla point is where.
Usually, the newer Grads still keep in contact with the Chapter as have close Brothers and Sisters who they keep in contact with.
Then a few more years go by and those who were close are no longer there so interest wanes.
More years go by and there is no contact from the Active Chapter, that Alum is lost.
Beleive it or not, The Alum Chair for Officer should be one of the main Chairs.
Suggestion, have each New Associate member have an Alum who they keep in contact with. Gives the Newbie a sense of History and makes the Alum feel needed.
Give updates on upcoming Ativities and make them early enough for planning schedual so can be there.
Keep Alums updated on GPA, Awards, Functional Awards, and anything else you can think of.
GPA?
I like ktsnakes idea but in the world of P C Risk Management, that is a gray area.

All members grades are imporant!
Dinner:
Steak for GPA +'s and Beans for GPA - s'.
If do not make grades, suspended from all social functions and voting privilages.
Realestate is Location, Location, the same principle applys here!
Beleive me, I and ohters have gone through the same thing.
I have been working with My Chapter for 39 years now!
One of the greatest things is when You as an Alum go back, they know who you are and you are welcome. Slept on many couches and beds over the years!
Seeing new Young Members progressing what you did or started there and see it still growing damn what a feeling!
