INSPIRE is a member benefit, and so can be accessed by members without payment, but do sign in first. Free enrolment is required to access a course initially. (Non-members are not currently able to access INSPIRE content.)
To access courses on which you are already enrolled, click: My INSPIRE Courses (top right) / View My Courses (mid right). This takes you to the INSPIRE Homepage.
To enrol on a new course, browse the catalogue below (narrow your search with the headings on the left). Courses are free for members, but you need to follow the enrolment process by clicking: Enrol / Register Myself / Proceed to Checkout (bottom) / Submit Order (bottom). Once enrolled proceed as above.
