Chip can delete any excess posts to clean it up and can sticky it and (I think) close and open it.
For this to work, I think we need one (or at the most 3) editors who will be authorized to post to the thread, update, solicit new info, make decisions, and coordinate the work.
If we decide to go this route, I nominate Puerhking, PolyhymnianMuse, Heavydoom, and Shogun89 ... oops that's already 4. Well, rather than nominate, it's probably more a question of who is willing to volunteer, and of course the appointment wouldn't be a lifetime burden. If the thread is successful, someone different will probably be doing the work two years from now anyway.
