"Your stuff" should display all places, where I participated - not just what I myself started.

The wish is granted today.

So, moderators may delete this thread.

One minor question remains: why the list of "Your stuff" still has a title: "Your Latest Content"?

It is supposed to be entire, complete, rather than latest.

I suggest to omit the word latest. Or a user may be mislead to think that this list is somehow going to expire by some deadline... That older items would get off the list, and the link to them would again be lost.

Or remove the title altogether. The name of the section "Your stuff" is enough. You may change word "stuff" to "content". But both are similarly awkward. Perhaps "contribution" would be more meaningful. Or "participation".

But renaming may wait till someone comes up with a more appropriate word.
