Well... you can download it now, a part at a time. That's the most recommended way of getting it at the moment. Be quick about it, because I don't know how long the parts will stay online for.
Cut dried etc, it will be over and done with within ten parts. Then it'll be on to a brand new radio series.
Downloading in one lump... nyet. Nope. And so forth. I'm considering releasing it on CD to buy through the website, and maybe one piece of merchandise, depends if there's call for either of them (see if you can pick it out, it's first mentioned in part 3) but besides that, download them as they go.
