Just curious what the exact meaning of the 2+2+2 is - I understand that it is 6 hours in total, but what do the individual 2 hour segments mean?

I think it's just a riff on the fact that its Jam number 222!

Hehe, yes that's true... Just wanted to make sure that there are no extra constraints :)

It could also be that people will work 2 hours each day when the jam is active. Like 2h on Friday, 2h on Saturday etc etc.
