Commas have also been removed for the same reason, There are about 57 o.
Contractions have been replaced by full words (for example, DON\'T has been replaced by DO NOT and CAN\'T has been replaced by CANNOT) in order to avoid apostrophes that would give away the Puzzles too easily.
The messages (except the a few math puzzles) are all famous sayings or quotes.
