PROBLEM: Review: Many parts of this book are difficult to understand for the beginning and intermediate user. It is an informative, advanced reference; the only one needed for an experienced website creator. There are no color examples of what the HTML language produces, making some of it difficult to piece together if you are not experienced. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: Jean Giorno assigned rights to this story to the public domain. Unscrupulous, evil American publishers are acting contrary to the author's intent and prostituting this work by cracking down on English language versions (including online versions), even new translations from the French. Don't give your money to greed heads who are 180 degrees in conflict with the principles of this book. 
 Polarity: Negative

SOLUTION:
True
