- @pecnut and @mscroggs (Adam and Matthew) tell Colin about @chalkdustmag
- Dave and Colin review the whole shebang
- @sparksmaths (Ben Sparks) talks about his musical MathsJam experience
- A round table with Peter, Dave, @dragon_dodo (Dominika Vasilkova), @mikegibson2010 (Michael Gibson) and an audience of hundreds.

Puzzles mentioned:

- Find three rational squares in arithmetic series with common difference of 5 (@kshancock)
