/flagged, /upvoted, and /favorites, with an "?id=<your_userID>" are how your own flagged, upvoted, and favourited posts/comments are displayed. "&kind=comments" specifically returns flagged comments, otherwise posts. For upvotes and faves, the argument is "&comments=t", for consistency one presumes... Favourites can be displayed for other users, upvoted and flagged cannot (for mere mortals). I suspect downvotes can also be displayed, though I don't know that syntax.
