Gombessa Worth discussing so that I understand a little more. I think your profile is primarily for other people, it just so happens that PMs got mixed into it.
So someone who wants to know more about you, clicks your nickname, sees your Bio, and then sees things you've posted or liked. Discussions is more of a filter on posts. This is similar to Piano World where you can see "Threads Created" and "All Posts" made by someone.
For yourself, you would just use "All Discussions" or "Private Discussions" or "Following" or "Bookmarks" in the top level nav... then you should be able to reach the discussions that you want.
I think it would probably be fair to make a case that PMs shouldn't be on your profile... that's just confusing.
