It may be too early to ask, but until moodle 2.9, I could see Guest Access option right in course settings, whilst in Moodle 3.0 it's no where to be found. Though I could still access it by going into Course Administration > Users > Enrollment methods , but finding it in Course Edit settings was more of a convenience than going way into Course Administration > Users > Enrolment methods.
Is this the way it is going to be in Moodle 3.0?
Also, why is there both American spelling (Enroll) and outside North America (Enrol) used? <-- I know his has nothing to do with functionality of Moodle, but just curious.
