I got the email saying that FW was closing (I was only ever an ereader.com/peanutpress customer) and I'm guessing because I'm not in the US or the UK there was no mention about transferring my purchases to a BN or Nook account. The Transition FAQ says I just back up the files on my bookshelf, so I'm not sure what I'm missing. Fortunately I did back up my bookshelf (and liberated it) when I got my PRS-350.
Cheers,
Simon.
