Yep there is the Pogs challenge.
I suspect there will be fewer participants this time round. Last time worked because of novelty and the month allowed things to gradually tape shape and things to snowball without the effect of people stashing before challenge start affecting stuff. But a month challenge is a long while and in my view something that should be at best six monthly, if not annually. Most of us will not be able to afford the resources to commit again after only 2 months lapse.
Myself, I'll still be folding as the last month of BigADV before that rig then retires.
