I had already suggested to have an option to read all of your own personal threads/posts, & an option to view all of your threads/posts you started a new topic.
Example:
Find all posts by MBHD
Find all threads started by MBHD
IMO, having this option you can find your personal posts somewhat easier than trying to use the search feature as Beater has said, it seems to not work very well.
MBHD
