Copy Edit the World

In my COMM 144-01 Organization Communications class syllabus the am and pm on the office hours don't have periods between them.

In the PRSSA Newsletter for 2009 there was a mistake on the third page: the sentence said I ran into an article by Kara Swisher of AllThingsDigital.She asks "Is Social Media Killing PR?

The picture is blurry but there is no ending quotation to the quote , no comma after she asks and the first letters in the quote are capitalized.

on my MCOM 72 syllabus for Diane Guerrazzis' class the sentence says :However, give yourself time to write the required paper( read on.)  The problem with this is that the period is on the inside of the parenthesis.
