I hope, Darren, that this morning's posting as a "reply" to your posting of
20th August is an aberration.

It wasn't, but there was a typo in the subject line, with "(20/08/09)"
instead of "(28/08/09)". If it appeared as though it was a reply to the
original 20/08/09 post, then your newsreader must thread on subject line
rather than on the References header.
