Ever year about this time the forums get questions and complaints about common reading plans. It is clear that users find setting up their favorite plans difficult and confusing. Rather than spending a significant chunk of programming resources to catch up with some online site, I suggest that you spend some time getting the rights to produce several popular reading plans as predefined plans. With the movement into the cloud and mobile markets I think this becomes a significant issue. I would suggest that you also add several Lent and Advent reading programs as the same issue arises then as well although not as strongly as at the start of the year.
