Ask Mrs. Wizard:
Please send me a personal email (firstname.lastname@example.org) if you have any questions. I answer all my emails and am more than happy to help any time I can. Your questions mean a lot to me, and may even inspire an article that will help others and make this a more valuable resource to anyone who reads it.
Manybooks.net note: You can actually download these books from your Kindle, directly from the web site. It is certainly worth clicking these book links and experimenting with your 5-way toggle. It may be a little clunky, but actually works fine. You will make good use of that free Amazon whispernet connection. The .mobi file format is my personal favorite for books from Manybooks.net on my Kindle, but you can also use .prc, .txt, and .azw files with no trouble. Experiment with them all and decide for yourself which formats you like the best. Manybooks.net books are always FREE!
