If it suits everyone, I'll agree with the 2 points. I understand Ultra when he says it's up to the creator, so we do as we please (and the one who doesn't abide gets lynched). Suggestion: maybe we should write it down in the puzzle to make it clear, and inspire newcomers to do the same.
Besides, I already had to give 2 points for puzzles, when a guy gives a partial answer -the make- and another (not waiting for the first to complete it) the model, for instance. It made me uneasy because I felt like "spending" too much points, but I saw no other way. I still don't.
