Liz,

The in-post search function should work. As you mentioned, click "Search Thread" located just above the first post of a thread, type in your search query, and click "search".

If that isn't working for you, can you please tell us what browser you are using and whether or not you have javascript enabled?

Alternatively, you can also go straight to http://v3.jvnotifypro.com/community_forums/search.php which is a dedicated search page.

Please let us know if this helps,

Mike Jr.
