Sorry about that -- should've mentioned you need to unzip the zip file. I've amended the wiki page.
Re: zip tools, the freeware 7zip is nice, if you're looking for a zip utility. It's for Windows. Not sure what zip programs are available for Macs.
Lately I've been rereading some favorite fanfics on a Kindle Fire HD and really enjoying that text-to-speech Play button. It's almost like having new audiofic. (I miss audiofic! It's been years since we've had any new recordings.) Kindle's voice is kind of robotic, and the pacing can be odd, but it's handy to be able to read eyes-free every once in a while.
