near the top right of the page right under where it says
Welcome bean see the
Quick links drop down list.
Near the bottom of the list choose
On your profile page choose
top of the statistics page you can list all your posts
or threads started by you.
Also if you are viewing a post you have made click your user ID
on the left. It gives a list which includes "find more posts by [you]".
This works for any post by anyone, not just yourself.
"list my latest posts" should be a quick link but hey, I just "work" here!
