Guest AHA - Sorry Lizzie, my alert system was lacking a bit.

I really ought to have recognised you there and I failed. You are now posting under such a variety of names it is hard to keep track. I ought to have recognised it as you when I said you were posting to something you clearly had failed to understand. Par for the course I suppose.

Not a problem - sorry WLD I would have loved to continue this debate - but it is impossible with Lizzie joining in under a variety of names and not reading people's posts properly. So I will respectfully cease from this now.

Well done Lizzie - you spoiled another interesting thread there.
