Angus -

A case in point is Thomas' recent post which arrived without me having seen the message that he was replying to. Perhaps I've enrolled on a sawn-off version of the complete list. Is this possible?

There are always on-going discussions and it's possible you subscribed after that thread started (depending, of course WHEN you subscribed). It also can be the fault of slow delivery of email. With this virus going around there's a lot of email out there and just like with snail mail your message can take a little longer to go through while others don't. You can always check the list archives if you think you might have missed something: http://mailman.xmission.com/pipermail/klf/ Welcome to the list! -paul
