Could the mods post a locked recipe that mods can alter even as they change and a date of last update with a link to this thread for continued discussion?
An index or database would be a better service to keep track of the posts that contain the latest recipe versions, not just for Heady Topper but for many other active recipes, such as Arrogant Bastard. The question arises, what constitutes a correctly updated recipe and what is just another variation? And who updates them in a timely fashion? Should indeed be someone with editing privileges.
A bad implementation exist already. Just looking through any beer's recipes on Brewtoad, for example, makes my head spin.
Here's another problem:
There are 2 threads listing 3 different recipes for Raging *****. They all claim to be "spot-on," where actually none are even close by themselves. Now parts of each can create a close clone.
