Will try the .pobi gimmick and see what happens with the Kindle Fire.

But at the moment, the Fire has the same problem, basically it does not recognize any periodicals as periodicals, i.e. all the navigational tools are missing. It treats them, and they function on the device, the same as books.

My guess is that the "p" in ".pobi" must be telling the new devices that the item is a periodical, and then the device engages all the internal navigational apparatus appropriate for periodicals. Very annoying way to do it though since that prevents emailing of these files! Would have been more agreeable to use some kind of tag and leave the extension alone.
