OK -- too bad looks like I will have to find another strategy.

Yes I guess that is an apt description  -- I want to pull rather than push.

I am not sure my skills are up to it --even with your help -- thanks for the
offer though.

My immediate problem is for the end of this week so even if I do poke around
I will not be able to do anything in the time frame.

Yes That is essentially the kind of thing I was thinking ( tranferring
security settings for folders without the folders themselves).
