This is an excerpt of my post in the private TB forum from a little while back when Jackal first brought this to the TB's attention:
I like the idea of a "wiki-thread" - but not sure if every thread should have the wiki-post concept. That's one of the things I don't like as much about FW...is the layout of the threads there.
Also, FT is more of a discussion forum than FW is (with the exception fo maybe FW Finance).
I think this concept would be best suited for car rental and hotel forums (and I can only think of the "discount code threads" - or a master index thread of hotel reviews, which some moderators already do a great job of handling).
