Getting back to school, or back to work after a summer vacation? If that means getting back to Apple Mail, check out the 30-to-50 percent discounts on a bevy of Mail-related products, including our “Take Control of Apple Mail” books. Other ExtraBITS this week include an explanation of why one of AT&T’s policies is bad for deaf iPhone users, an explanation of Dropbox’s two-factor authentication, and an interview with Tonya Engst on MacVoicesTV.
 -- A number of developers of Apple Mail-related products have banded together for the “Get Back to Mail” promotion, offering 30- to 50-percent off through 11 September 2012. Our “Take Control of Apple Mail” ebooks (for Mountain Lion, Lion, and Snow Leopard), all available for 50-percent off, join such worthy Mail utilities as SpamSieve, MailTags, Mail Act-On, Mail Perspectives, DockStar, Attachment Tamer, MailHub, Mail Stationery, ForgetMeNot, Letter Opener Pro, SignatureProfiler, and EagleFiler.
 -- Over at Wired, a deaf iPhone user explains precisely why AT&T’s decision to take a core feature of iOS 6 — FaceTime video chat over cellular data networks — and make it available only to those with a shared-mobile plan specifically harms the deaf by forcing them to pay a higher rate with no associated benefit. The same argument is valid for all subscribers, but has particular resonance for those who use sign language.
 -- Before leaving on vacation, Tonya Engst spoke with Chuck Joiner of MacVoicesTV about a variety of topics, including the need for Web site redesigns, how Web site design differs from ebook design, how our current publishing process works, and the new Apple hardware she’s using to make it all happen.
