General wish: could you bundle the Challenges as (free) mini-programmes?

Well, the headline says it all: could you bundle the Challenges as (free) mini-programmes?

I've suggested that before but I'll just keep pushing this idea, if you don't mind. I think it would be good to give people a way to test the features of the calendar and the paid-for-programmes (miraculoulsy the calendar fills up with suggestions which you can - gasp! - re-schedule without messing up the whole schedule etc.)

I assume one counter-argument would be that people might end up scheduling those only but I don't think they would, actually. (If they do, they do so already ...).
