what about a getting there part where movies that have been looked at and people tried but no success and are getting close it would allow you to weed the older posts out and still let people see what people guess with no success thats my suggestion
As films are solved (and after the OP hopefully acknowledges) they are moved to the Solved sub-board. Films that go for a long time without a solution are moved to the Unsolved Archives. I do need to do some housekeeping there, but that is the current system - and I am afraid that I believe it is already complex enough.
