Talk About A Duhh Moment!
I just had a “Duhh” moment!
It seems I had one of the Pro configuration columns set wrong in the system. I thought I was assigning 500 credits for each new signup. I didn’t realize the system read it as 500 multiplied by whatever the free signup bonus is!
I did a double take when I noticed 25,000 credits for signing up a new member!
My bad! 
I apolygise if this discourages you from sponsoring. But, heaven’s to Betsy, I was giving away the house!
It appears to be “all fixed” now.
Please drop me a support ticket if you notice little goofs like this. I’d appreciate it. Thanks.
Happy Hunting!
