Hi,
I have an iPad and GoodReader. Does anyone know if there is a way to export annoations from a PDF file.

I often receive updated PDF versions, and instead of replicating annotations in each new version, I was wondering if anyone knows if there is software otehr than GoodReader which I can use, which will allow me to export an annotations file, or do something similar, so I don't lose annotations between versions?
Any advice is appreciated!
Thanks!
Lesley.
