The best way to greet a new affiliate is to let him know the benefits of becoming EA2.
Next to teach him how to be atleast EA2 every month with least cost.
Next to teach him to build a team of PSAs without which there is no use of being EA2 or teamleader yourselves.
Lastly how to teach his PSAs to repeat whaterever is mentioned above.
That is all it takes to succeed in SFI
