Eezz Writing - Red White & Blue

RW&B is 'The Art of Punctuation.' Is 'Rule 1' of The Elements of Style controlling? The power punctuation marks are identified. The full stop marks are identified. (Do you know them all?) When do you use a comma to separate two sentences? Is -from the $600s correct? Should you use periods with acronyms? Should you use (. . .) in your own emails? Should you place the hyphen in the trashcan? Is the (: ) an arrowhead? Is the 'Crown Comma' the semicolon? When do you use a (;) in a sentence? When do you use an en and em dash? Should you use the Oxford comma? Are you confused? All the answers are in RW&B.
