For me I keep both ny white slips and the pink ones. Reason is to track how much I am giving and also recieving. I literally keep them where I can see them in my truck (AKA Office) and visit them through out the week to make sure connection is made.  The keep them all in my roster book and once I know it was made i put a check make on it.  I only contact the memeber to see if connection was made and not the prospect because I dont want crediibility to be lost if something may have happened. As my recent coach told us I want to keep the triangle as it has much more success if I am involved as oppesed to me not being apart of the connection.
