This is Big Brotherish. Look, I'm afraid I agree with Princess Platinum; I think this could do the opposite of what you want, Gp75. The login information, at least, is already done in Special:UserList, and Wikia's cookie logs you out in about an hour or two of inactivity anyway.

It's a good idea for an extension, however. :)
