After looking at the features of WatuPro and the features of Namaste, it seems like there is a lot of crossover. What does the Namaste plugin offer over and above WatuPRO?
Also, both plugins look to use login capabilities... are those simply additional users (with set roles) within WordPress? Can either plugins (WatuPRO or Namaste) instead be integrated into a WordPress installation that has a full membership site plugin (like WishList Member) so that users wouldn't have to essentially log in twice to access exams and then other "private" posts/pages?
