Looks to me like anyone can edit it, especially since it's a "community" page. Something to consider is that official-ish pages like that have usually been thought out a lot, and they tend to be the way they are for a reason. So before you make any edit, ask yourself if there might be a reason nobody else has made that change yet.

But in the end, it's basically a Wiki page, and anybody can just revert your edit, so have at it!
