Grif is right, if we're going to attempt this it makes much more sense to use a hierarchical wiki rather than a linear thread. I do worry that the time required to build something this significant (even if it's not an encyclopedia) might far surpass the amount of time it takes a new member to learn to use the search engine (even by trial and error).
I'll contribute to whatever we do, but maybe some historical research is warranted before we go off in any one direction.
