Glad you found the thread.
More as a PSA for anyone else with this particular issue, it's always good to remember this helpful tool -
Type (into Google) "site:forum.mrmoneymustache.com <your search term> <additional search term>"
You can also do this with other sites that have subpar internal search functions, although it works best on forums, blogs, etc. Just replace 'forum.mrmoneymustache.com' with the site you wish to search.
