I'm not sure if it would fit best in Career & manager tools, but I think it would be helpful extremely with some guidance around Board member/Advisory board / committee member guidance. I think many managers get's involved in a lot of these different activities and a lot of us I'm sure could really use some helpful guidance.
This could be both suggestions for people on how to get involved/more involved with these things, but also what to do in these roles and how to get essential knowledge. Different countries different styles and things you need to know I'm sure, but some overall guidance would be very good.
I'm sure you guys have a lot of cast's in the queue, but I think this could help a lot of people out and in the 413 (yes high C!) cast's I have listened to so far there havent been much mentioning of these things.
