Thank you so much. I extracted the apk file and used the Wifi File Explorer to move the file over and installed it. It immediately asked me for my SendToReader username/password and did a verification test. It is working just great on the Silk browser. I am very happy to have it because ever since I've had the Fire, I've been doing most of my browsing on the Fire and have been missing having SendToReader.
I also want to thank you for your explanations at the Alternative Android App Stores and Markets thread. The explanations are so helpful.
Thank you, again -

Let us know if it works. You may have to try a couple of browsers so don't give up if it doesn't work on the Silk browser.
