Yes this is good, but it only shows posts in one subforum. For example it will show me what I have posted here in 'Help and Tips', but not what I've posted under 'Civilization 5'

As you read this response look just to the right of my name and there is a little down arrow. Easy to miss on first glance but you have it too.
Its a popup menu. You can 1)read all their posts everywhere including their profile page or 2) simply go to their profile page.

Unfortunately unless they post on these discussions at least once you can only find yours on your friend activity/my activity page. The link for this is not actually on your profile page. Even typing the link to look at someone else's entire history doesn't work. Even if you add this as a clickable link on your comments section steam will instead redirect you to your profile page.

Oh, and if you delete a post or report a user it still shows on the history. Unfortunately chatrooms conversations do not show up on this list (if they even record that).

Have fun!
