Okay, I received enough responses (mostly off-list) and it seems some
updated documentation would be of value. I agree with Arthur that an
operational admin guide would be useful (if I had that now it would
probably save me the work I need to do).
Also, thanks for the great list of questions - I will try to incorporate
them into anything I create (even if it just identifies the question as
needing to be answered).
