I agree with twilight, the search function is very unreliable at best if it works at all.
I've even partially remembered the name of a post that was on the site within a week and gotten nothing close to it in results and had to go back manually to find it page by page.
Then to top off your frustration when you post your Q since you cant find the answer someone usually flames you for not using the search function.
Perhaps someone at PCT or their webmaster can get this working correctly???
