this is a fine product i will use it joyfully and gratefully. i like it that it was loaded up with extras, like the charts and chapter K. i look forward to chapter P.

so far, i have only found one thing i would have done just for asthetics and consistency. it concerns the links that are in red. some of the links are bracketed with black like this ( ) some are like this first black and then red, some are red and red.

its a small criticism, over all i am excited to have it.
