I send my CSAs the same information I send to my PSAs.
I had a great sponsor, and then got reassigned to a sponsor who has never contacted me. My co-sponsor, though, has been a lifesaver and is always there when I need him. Shouldn't I give that back to my CSAs?
I have no idea what other help they are getting from their upline, and besides, I made a commitment to them when I accepted them as my CSAs.
