Well, by offering tips and advices all the time. Letting them know it's important to converse and exchange informations for the good of both. Also, show them pics of your comission report and your earnings, when they see that they will definitely want to talk to you:) Plus, if an affiliate is really interested in this job, he or she will converse without any "pressure" from you. For those who need a little push up, you step in. Good luck!
