The empires wiki is back online, but as a precaution it's a completely fresh install with only the articles and images transferred over. This means that all old user accounts are gone now and new user account creation is disabled. If you wish to be able to edit the wiki then please send a pm to Beerdude or Trickster and have them create an account for you and add the account to the 'editors' group. I would also advise that you choose a user name identical to your old one so that you pick up your old talk page and page edit credits.
High likelihood of most of them being not real users. Cross reference posts/edits vs user names and you will find most did nothing or were possibly dormant bots never activated. I had to wipe out most of a wiki user database the other day due to tons of users who were clearly not real users.
