No, I really think you're onto something there, Markus. All you need are some mugs to support it and, guess what, here we are!
It's a difficult concept, but all we have to do is post, then hope someone else will post so we don't lose. And if somebody posts who we don't like, then all we have to do is not post anymore and they've had it! It'll be like a gentle version of Russian Roulette.... we could even wear our pyjamas!
