Check Your Writing!

Check your Writing! Did I proofread my writing for spelling errors? Does the first letter of each new sentence, as well as each proper noun (the names of people, places and things) begin with a capital letter? Is “I” always capitalized? Does every sentence end in a period (.), question mark (?) or exclamation point (!)? Did I put one space between each word and two spaces after each period and between all sentences?
