A blurb worthy of a book jacket

I just posted forall x version 1.23 
The update was prompted by a recent e-mail from Nathan Carter, a math prof at Bentley College. He began:
I used your textbook in a logic course I taught this past semester and found it very helpful. It is readable, clear, and addresses lots of essential issues without getting into more background than is needed. The students and I both thought so. Thanks for making it available free!He went on to point out more than a dozen errors in the text. Most were inconsequential typos; others were consequential typos. All are now corrected, and Carter is added to the acknowledgements.
