If there's something thats part of the game documentation (on the doc pages) that isn't there and should be, the discussion pages are used to talk about it. Certain information (like formulas) are not within the scope of game documentation, and all those formulas are player submitted.. well most of them anyways. So the discussion pages can be used by players to discuss the formulas associated with those things.

Edit: If anybody wants, they can make a specific page for formulas.. I mainly used discussion pages as a temporary fix so the info wouldn't get 'lost'.

Some pages are protected; that may be why you don't see edit links. If something is missing or you would like a correction made, please use the discussion pages.
