I was just talking with @Adam Czajczyk in live chat regarding the CoursePress Pro plugin. I think that adding a feature into the next update would be really useful:
Allow Automatic Enrolment to one or more course after signup - Perhaps linking to the Membership plugin so that
If user1 registers for membershipA then they are enrolled on Course A & B
if user2 registers for membershipB then they are enrolled on Course C ... etc.
I see this as simplifying the process and improving the quality of the experience for both website owner and website visitor/member (hope others agree)
