I wasn’t aware of our ability to control this. I’m thinking I’m not alone here. Perhaps the default action should be in favour of the affiliate rather than against them. That is, the popup works as a cross referral for us and if we don’t want it then we can use the no popup option.
Just seems a bit devious to me that unless we contact the affiliate manager (which implies we must know about the options) to ensure we are receiving the proper credit.
