The first thing that comes to mind is: Everything that is in the faq and guidelines, because no one seems to read them anymore. And it would save us from one or two how do I make a link or bold text.
Awards seem to confuse people and could use a place to be explained (not giving the answers away obviously). References/links to user generated content would be nice, like RaR, the campfire chatroom, etc.
I’m tempted to say the moderation process, but I feel like that would become a mess if people can edit it freely..
What else.. history about the site and founders, meme’s and ongoing jokes, userstats and visitor data, technology behind the site, known bugs, etc. etc.
