Just explain to all of the Alums that you hve E-M for that this does not mean all of them! Only the few that come in and Trash Their House, and I gaurentee they will be Pissed also!
I have 1/3 of the e-m of my alums as I have been working for 2 years to get them and am still finding them today!
This is how you keep in touch as best as you can and the cheapest!
Of course there will be some that do not wnat to be contacted and that is their fault not yours!
Hang in and do what your heart tells you to do that is the best guide!
