My Replies/Comments

Here is a situation; I replied to a post, blog, forum, something, and now I can not find it again.  I made an error in the reply and would like to correct it.  Is there a way in Dolphin to have a block in the account page that would show recent replies left, or to show which posts that one left replies on?  I would think you could do this similarly to the way the timeline shows replies left by your friends.  I need a timeline for the member to show the comments and such they have left.  I was a member of a social network that had this feature, "Replies I have left" and it can be handy at times.
