If you gather a committee, write a draft document, and solicit feedback, you might receive scores of revisions in email and on paper. Compiling all those changes back into a single coherent document could be a long and tedious task. On the other hand, you could create a wiki. That would enable everyone to work on the same collaborative document and compile changes on the fly. A wiki is basically a read/write website open to anyone with permissions.
