The Byond ref is always very helpful but there are plenty of things that aren't mentioned. When I'm reading a reference I would usually want it to include every little detail about everything. I know it probably takes a lot of work to maintain the ref, so why not allow people to contribute to it themselves?

I'm not sure if there is an easy way you could allow people to contribute to it or not, but one option is just putting the ref itself on GitHub or something and handling it through that.
