The following may be good ways of recognizing the achievement of your PSAs/ Downline.
You may recognize the achievements of PSAs by giving them a few TCredits or Gift Certificate, when they reach EA status for the month. Also, congratulate them on their efforts reaching the EA status and offer guidance on how they can get to Team Leaders position. If you are able to develop a personal relationship with some of them and have access to their cell phone details, then a call will also be nice.
