You've ALL got stars - oh dear, now form a little line!! Lol - because you've answered. Thing is you see, rofl laughing about my "coal powered abacus"!!!! - it takes me so long to get back here to reply to you all, that you're all worth the bl**dy things just for being so patient!! Hello again - oh, but knobby and dris - it's a "pleasant" thread here. No falling out tonight, because I won't be on tomorrow - oops, tonight again now, being as though it's Saturday already - and I can't be doing with reading any more arguments. NOW then - who's got a drink for me?!!
