FollowOCW lets you:

• Discuss the OCW in track based forums.
• Set questions for others to answer (to check you’ve understood a lecture).  Once you’ve answered a question then you can see everybody else’s answers and discuss them.
• Let people in Twitter know where you’re up to so they can join you (just don’t tweet too much – that would be annoying).
• Use LaTeX markup (because physics and maths will need equations).

What do you need?

You’ll need either iTunes or an iPod/iPhone with the latest OS to get access to iTunes university.
