SX50 E-book by Stephen Ingraham???

Did Stephen change his mind? He started an E-book awhile back, wrote 12 1/2 pages, then, nothing.

As a very new beginner to the SX50, & photography, I enjoyed what he'd written so far, enjoyed how he wrote, & found it very educational.

Then I got sick, wasn't able to come by here for a spell, & now can't find it. Did he change his mind? The 12 1/2 PDF pages I downloaded, all there's gonna be?

Thanks,

Felix
