A discussion forum is now available at ibphysicshelp-community.net. Here you can find up-to-date information about the coming episodes, ask/answer specific physics-related questions and find various resources (websites, books, etc.) that other students found useful in their study of physics.

UPDATE: Due to lack of time for maintenance and relatively low forum activity I decided to close the discussion forum. For up-to-date information about this podcast and other useful IB physics resources follow my Twitter feed.
