Yes...I saw that FREE ISSUE, too, and went through the download process. But once it was downloaded, you couldn't 'SAVE' it to your computer without ALSO installing the 'reader software' that opened it for the 'online read'. Meh. I didn't feel like downloading the reader software in order to 'save' the digital copy of the issue. Too many steps.
I suppose IF a person were 'subscribe to' the digital version of Knitters, it would be worth the effort to also download the 'reader software', and prolly mandatory, too. I don't know. I think Knitters should make 'the steps' and 'rules' more clear. I'm assuming 'paid digital version' would follow the model set by the free digital version.
I subscribed to Verena's digital version for one year, and it was much simpler. Very nice. I saved every issue. PDF, which I like to use.
I now subscribe to Knitters, Interweave Knits, and Vogue. I like Knitscene, but you can only get them at bookstores or LYS's.
