wow, that is lousy! (I wish I knew that an hour ago).
That just doesn't make sense. Why would Mobipocket Desktop give you the ability to edit this metadata if it didn't make any difference whatsoever on the device?
(Or did this work only on PDAs but not e-ink readers)?
That's saying that the metadata is baked into the binary file.
Creator, as I understand it only has the ability to import html files. It doesn't even have the ability to import ms word file. so essentially the only option would be to convert from MS word to html. that's strange.
I downloaded quite a number of manybooks prc files a year or two ago.
