First of all ,to focus your downline or PSa on duplication you must tell them-
keep your status to EA two and more months,find 5 people and teach them to do the same thing as you!
Teach this five people to become EA and hold that at list two months.
If they do same as you,this is duplication.After that 5 people ,every PSA find again 5 people.5x5 is 25....this is main job,this is mail story...this is duplication and at the end ,this is glory!!!
