This is a bit weird. An unregistered user asked a question here. Then instead of editing the question or adding comments, he started posting additional informations as answers. When I first noticed this I left a message telling him to edit the question. Then I noticed that the user number changed for him. I.E. he was no longer responding as the OP. How do we deal with a situation like that? Why did it happen?

In this situation, can the OP access the unregistered account to manage the question at this point? I'm at an absolute loss!
