Quite a few (OK, thousands of) old threads were deleted a couple of months ago, in an effort to reduce the load on the server. The one you refer to may have been one of them. Not only that, but the archives have now been re-merged with the main forums. I'm assured that the new software means that we can now cope with full searches at pretty much any time, and the forthcoming new server should improve things still further. However, if you have problems do let us know.
