OK but why isn't there a auto sync with maxpreps? Is it in the works?

MaxPreps does not give us a way to an auto sync. If you (and other interested users) can contact MaxPreps and ask them to give us the ability to do so, we would. It would likely require them seeing a demand from their users to allow it.
