Ever since the vandalised wiki pages that happened recently, we need the wiki to include who edited the wiki page or else it would be harder to identify the people, especially vandals, who are responsible for editing the wiki changes. We also need update history as well, in case users use a bait account so they can get "banned" without getting banned. With the update history, it would be practically impossible for vandals to use the bait trick. And finnaly, a report button for vandalized wiki pages so developers and moderators can get inforation quicker than before.
Thanks for the info. Also, if your ability to moniter is broken, then it's best to use add a report button tool!
