I fear the amount of people who will just delete entire sections by editing to troll, of course we can ban them and save back-ups for every page to avoid losing info but it's time-consuming ... How much of this happens on the unofficial wiki? I don't really go there so I'm not sure.
... Anyways overall I think it would be good to have the wiki in a visible position so that new players can get background info on the game, we just need to be careful about how we allow editing rights to prevent trolling.
