Agreed that disincentivizing current contributions is a risk; possibly the biggest risk. However, few, if any, of the existing tool builds posted on the forums are detailed enough to qualify as plans. This system might actually increase builds posted on the forum, because people could make those same posts, but at the end of them, offer full detailed plans; the post itself acts as kind of a free preview for the full plans. Currently, I think the main incentive for people to post tool builds is peer recognition. Peer recognition is a really noble motivation, and it produces great results, especially when you amplify that recognition with awards, trophies, etc. It's a strong enough incentive for people to post 10 paragraphs of text and 10 photos, but it's not a strong enough incentive for someone to also put 10 or 20 hours of work into making a detailed set of plans. For that sort of time investment, we would need to fairly compensate people. Nevertheless, loss of our current positive atmosphere is a risk, and now's the correct time to mention it.
