Possible Duplicate: How can a question be closed by a single
(non-moderator) user?  I've noticed a few people closing their
own question as "off-topic", like here, here and here. I didn't
even know you could close your question by yourself, and it
seems strange that it's happening at all.  Did I miss some new
announcement?  Edit: Actually I see that these are very old
questions, so now I'm even more confused. Also there are many
more examples, just do a search on SO for closed:1.
