Can anyone help with WF search problem?

I don't think I'm awake yet - or else I'm not who I think I am on the WF

I tried using the search link on the red bar at the top of this page to search for posts under my user name.

No matter what I did, there were no posts found.

I'm trying to find a post I submitted to the WSO forum last night and it seems to have vanished off the face of this forum.

I also can't find the link to view previous posts I have started, and posts that I have left in other threads.

Can anyone shed a light on what I am doing wrong? I know I have used this feature before. I think I previously accessed the info by clicking on my user name within a post or thread. However, I can't find any of my posts to click on as the only post I have made recently is the one in the WSO forum last night. (And the WSO was an old one - and I don't know the title.)

Val.S.

Edited to Add: I just clicked on my user name in this thread and found the post I was looking for.

However, if there are no recent threads posted, how do you access your information?
