Your A2A list gives you an opportunity to network, and share strategies with
your fellow affiliates. Also each country has their own specific problems or
restriction and the affiliates in the same region as you may have a work around many
for the problems, that the new affiliate, in that region may experience.
I always suggest to my new PSAs and CSAs to join A2A for those reasons and the friendship.
You can never be to rich or have too many friends.
