If a question is closed but then later the edited, how do you go about re-opening it?

I came across [this question](http://superuser.com/questions/818346/unable-to-open-outlook-2010-on-windows-7) in one of the review queues.  Originally, the question was basically just "Outlook won't open".  So I posted a comment asking for more details.  The asker responded, but not before his question was closed as "Unclear what you're asking for".

I edited his question to include the information, but I can't go about answering it because it's closed.  What's the process getting questions back up for a re-open review?  Not just for this question, but closed questions in general?
