Badpuppy is still on my todo-list, but now I am going to be afraid just to start with it.
I can understand the feelings of Ben, YOU are doing the work to keep members stay and not the affiliate. But if you offer commissions on rebills, you have to pay them. Otherwise don't offer this. For most of our sites we don't offer commissions for rebills, because of this reason.
On the other hand, for an affiliate it's not very interesting to promote a site without getting payed for rebills.

I like the way Lisa goes. Contact you affiliate and discuss it with him. Many of the affiliates need a little kick and help to be a more active promoter for your program (I am also a kind of this affiliates )
