When viewing a thread, there are 2 new additional options in the search thread pulldown. The first one searches and displays a list of posts made by the thread author (aka OP). The second option searches and displays a list of all posts that you've made in the thread.
And just in case you missed the previous announcement we've also added these additional search options:
1. The Google Site Search - at the top-right corner of the page - enables you to search both the blog and forums in a single query.
2. Find My Posts and Find My Threads is now in the search pulldown.
3. There's now a checkbox in the search pulldown that enables you to search titles only.
4. Find unanswered threads in the search pulldown displays the past 7-days of unanswered threads.
