Things have finally improved slightly with Advanced Search (after about a year or two of users pointing out that it wasn't fit for purpose!).
So if you now AS your name and find a thread you posted on and click on your username on the posts that come up in the search, the function will take you directly to your post (rather than just the top of the thread) as long as your post is on page 1. If it is on another page further on in the thread, you cannot go directly to it. You still have to click through the pages and do control find on every page manually. Which is very tedious.
Are things better for you Premium users?
