Right now, about the best you can do is to right click on your own name in a topic (like this one).
That will take you to your public profile.
On the lower left column of the profile you'll see an option called:
Access to the whole list of his/her messages
That will take you to a page when you can see the sections you've posted (drop down menu at the top) and for each section you'll see the topics you've created and also the topics you've replied in.
