User story:
I posted something today, and an hour later saw someone posted the same thing earlier than I did. I wanted to return to my post and edit it. Rather than hunt through recently-updated threads, I'd like to click on a link for "My Posts" the same way I can click on a link for "My Messages"
Similar feature:
The "Search" feature can have username as criteria, but "substring of body text" is mandatory so it would only show my posts that each contain some word. Better if I could search on just "{author: $self}" instead of "{author: $self, body: /foobar/ }"
