bravo Gianfranco !! excellent work ! i hope that more people will also write to publishers as you have ; i think this can make a big difference. please do let us know if you have any reply. and as haridasi said, please do look into epub, which is the new ebook standard being created : it will soon be supported by the Cybook (i see you have a Gen3) and is a much better and more powerful format for ebooks than mobipocket. and if you still want mobipocket, it can easily be converted.
