One need register only once for an account although the account data can be changed at any time using the Modify Your Account bar on the main page. First select the institution. The former is akin to auditing and unlike registration does not require the instructor s permission. The difference is that no lines of communication are opened to the instructor and the students records do not appear on the instructor s class roll. If a student who is browsing is subsequently admitted as a registered student then all of the work done to that time will appear in the instructor s records.
Students can also drop a class.
One effect of this is that a student can move from one section of a course to another with the records transferring seamlessly. This has the effect of changing the student s status to browsing with registration pending relative to that course. Aside from simple record keeping the fundamental difference between browsing and registration is that the teacher of any class in which a student is registered can change the password . This means that any teacher of a registered student can assist the student with a forgotten password problem. It also means that students not abiding by the rules of a single teacher in whose class they are registered can have their system privileges frozen by that teacher.
