So…

He ran out the door. SENTENCE
After he ran out the door, EXTRA IDEA

It’s a sentence even if it’s short or unclear.

5.  Using unnecessary apostrophes with the letter “s.”
Here’s a quick lesson: Use apostrophes only in contractions (don’t, can’t) and “of” ideas (Mary’s car, Tom’s schedule).
Apostrophes aren’t decorations, and they don’t mean more than one!
So…

The cars will be replaced in two years. (no “of” ideas, and no apostrophes)  CORRECT
John’s laptop isn’t working properly. (laptop of John)  CORRECT
The Browns are taking a vacation next month. (no “of” ideas, and no apostrophes)
My uniform doesn’t need to be dry cleaned until next week. (don’t is a contraction)  CORRECT

    Should there be a period after bullet point #1? “Not ending a sentence with a period” is not a complete sentence; therefore, it should not have a period after it. Correct? The same would be true for the other #s.

    You have a sharp eye, Ashley – and you’ve raised a valid point. Technically there shouldn’t be a period after the bullet items. I made a kind of “executive decision” to use the periods anyway because they seemed to look more professional. Because bullets are associated with business writing, rather than academia, many writers say that it’s ok to be flexible about punctuating them. I’ve put myself in that camp.
