I think there should be a wiki post, the second post of each thread, that could be edited by any member, after a thread grew too large. That would consolidate information and facilitate searches.
So a thread asking for info, would only post a reliable info/solution in the post no. 36, on page 6, that would be copied and pasted back into the wiki right after the OP and so on.
All the forums that have that system seem to work fine and it's very easy to just look into the wiki post and see if there's anything worth to it.
