@madhens: I’m still met by “OpenID error: Nonce already used or out of range.” when trying to login to https://wiki.ubuntu.com .
May be worth mentioning that I have never been a member of ~ubuntu-wiki-editors, since I became an Ubuntu Member before that team was invented. And as an Ubuntu Member I have still been able to edit the wikis. Can that possibly be related? Do Ubuntu Members no longer have automatic edit access to the wikis?
