Thought I'd mention, for what it's worth.
My girlfriend has a subscription to the wall street journal, and we share my amazon account for kindle downloads. I was not able to find a way to have the newspaper delivered every morning conviently like it is to her kindle since she's the one who subscribed, but I was able to go to the kindle website, and then click "manage my kindle" and then under the delivery status bar to the right click something that said something like "your digital library" or something. It let me then not send wirelessly like I can with the other books we have, but instead download to my computer. Once I downloaded the file to my computer, i transferred it to my kindle, and was able to read it. I am not for sure but I imagine it would be the same with the magaizines.
hope that helps.
