[@MatthiasAngel] considering a collab is literally just a long seeks of posts by two or more people, I can't see the issue. Deciding who wins was simply a suggestion, but we'd expect soneone to know if they've lost and make a proper judgement accordingly. Plus collabs remove the need to have multiple consecutive posts replying to each. And considering that the GM can come over to the pad and give suggestions/criticism before it is posted, it should in theory solve the problem.
