Further, it's near impossible to effectively write all your JV follow-ups prior to launch. I mean, the excitement of the launch itself is what you want to convey to your jvs as it's happening.
For instance, what type of conversion rates (overall), what the top affiliates are converting at, etc. You really want to stir up excitement in the follow up series, in my opinion.

This can often motivate affiliates to push a little harder, to get to the top of a leader board and/or win some bonuses.
