As mentioned in the other replies, even updating and keeping up with the new content in RuneScape 3, as well as replacing long since changed content, requires a substantial amount of effort. Theoretically, if we wanted to create more pages, i.e. Firemaking Training [OSRS], it could work, but then we have a major links problem. All of our tooltips and such are linked to RS3 databases, so someone would click on maple log and be brought to its information in RS3. We don't have any sort of framework for OSRS databases which is probably the first thing we would need, and I'm not sure building one would even be possible. Even if we were able to extract out the old guides from Waybach Machine and got flooded with submissions and useful information to add on to and improve them, it's still an issue of sheer manpower. It takes time and effort to modify, code, check each page and verify that information is true. For the obvious security reasons we are unable to let people write and submit a page. Few of us actually even play Old School. So while it is a nice idea and something that I wish we could do more of, at the moment it just doesn't seem possible or practical. The intersection of people who have the interest in RuneScape, the ability to code or willingness to learn, and have a significant amount of time to contribute is just too small.
