On the old board (*sigh* ... I know, I know) the "View Your Posts" option actually showed you your posts, in chronological order (newest to oldest) and gave you the option to view each one in context by jumping to the relevant thread.
Now, it shows you a list of threads to which you've contributed. If that thread has multiple pages, you either have to plough through the whole thread, or hope that you can remember roughly what stage you made your post.
In all honesty, it's quite a big step backwards in terms of functionality.
Cheers!
