In addition to the standard page elements on each course page, course owners can provide links to all kinds of additional, presumably related, materials. For example, an owner could include an element called “Course Information” which, in the case of an academic course, could include links to submission guidelines, sample exam questions, or even office hours. Such information blocks are completely customizable, their appearance and content entirely at the discretion of the owner. All page elements can be moved and changed in various ways.
