... Tao sounds interesting I'll check it out.

BTW A bit of spam oneupmanship coming in (if there is such a thing?!)... a while back we received 15,000 e-mails all exactly the same from the same source! We eventually managed to put a block on the e-mail address it was coming from but, boy, it took around 10 hours to clear it all out.

Thanks for the extra info also RAMWolff, this program looks like it would be very useful.
