Thank you very much for this response, Steven, this was just the sort
of information I was after. I had to smile at your suggestion of
getting the whole company to collaborate together - after numerous
mergers, takeovers and joint ventures, I'm almost unsure of who I work
for on a day-to-day basis - we have a "company" that consists of
clumps of administrators zealously guarding their own personal
kingdoms - getting a text file transferred can be a major headache
these days! :-)
Cheers
Nick
