@lirtosiast @Zgarb @Sp3000 @Dennis @Doorknob: I've finally sorted out all the prizes for the Best of 2015. It's mostly bounties, except for Zgarb's challenge. I think we shouldn't put up all the bounties at once, because that would just unnecessarily divide attention between the winners. In any case, the bounties should be put up for all 7 days and the bounty text should link to both the meta poll and the answer the bounty is going to (for answer prizes).
Since lirtosiast is offering two bounties and Team Effort is getting two bounties, I'd suggest we start with those. And Zgarb can post his challenge any time now.
@lirtosiast Also, (provided you don't have any objections to the above plans) could you start with the Educational bounty? Because Peter is getting two bounties.
