FOR, do your friends realise they can revert to their previous version?
Thanks - however I think the time had well and truly passed by the time they had talked to me about it.
The office / network installation has been pretty well sorted out eventually, and I doubt that they would turn back having done all of that work. They're accepting of the fact that this is the way it will be, so having made the move, and sorted out the challenges (as far as I am aware), it was going to stay that way. It's a 'serious' office network in the National Capital (yep - that serious!), the machines are work horses to do the job, extensive written material is their tool of trade, and there is too much at risk to fiddle beyond the minimum necessary.
Thank you again,
FOR
