Not sure what's going on with this question: http://mathoverflow.net/questions/28400/question-retr. Is it related to the recent delete-undelete stuff? I was tempted to rollback the retraction, but figured that this would just lead to an edit war. All that will stop that is a moderator rolling back the question and then locking it.

To help avoid a delete-undelete war, I just went and voted for all of the answers. Not sure if this pushes them up enough as I'm still a little foggy on the rules.
