David,
Thanks for all your efforts
We will take what is given,
'As is',
no pressure. (If you believe that? I have this bridge....)
I would guess 95% of my use is the Webpage (mostly use Fantastic Fiction)
with a tiny bit of CSV
I also don't use it frequently. Mostly when a new book comes out that belongs to a series that I don't already track and I back fill the info on the other books.
BR sounds like your best candidate for the full wring-it-out test because of his stated frequency of use
again
