If you click on your username, public profile, and then statistics, you can click to show all posts or all threads started by you. For a recent thread/post or for someone without many threads/posts, this is the quick and easy way to find something you've written. In fact, you can also skip the profile step and from clicking on your username go directly to a listing of your recent posts.

It looks like the post was moved to a consolidated thread on Hawaii service in the AA forum.
