I'm trying to find the Sticky thread I started about my stolen laptop back in April, so I can get some information off of it. I can Post Search every thread I'm on except that one. Would someone have deleted such a thing? Please say "no."
I suspect the broken search function is the problem here. It appears that posts from approximately 13 Jan 2006 to 27 May 2006 have not been indexed for searching. The posts are still there; they just don't show up on a search. These dates are based on searching for my own posts, as well as those of a couple of frequent posters. Take a look at this search for your posts; scroll about halfway down and you'll see a jump in the "Post time" column from 11 Jan to 31 May.
Just by going back through the regular forum pages, I think I found the post you are looking for.
