@scottalanmiller I couldn't find a way to mark the post as closed/ answered. Do I need to do anything to shut this one down?

It's currently marked as a discussion rather than as a question. In theory you can use the Topic Tools and "Mark as Question". Once it is a question, then you can go to an individual post and mark that one as the answer OR you can use the Topic Tools again and just mark it generically answered.
