There are several comma rules, so here are four to start, and the rest will be covered next week.
Use a comma to join two independent, related sentences.*
Example:
The rivalry between the Chicago Bears and the Green Bay Packers dates back to the early days of football. The Bears have won more of these match-ups.

Use a comma to set apart an identifying phrase in a sentence.
Example:
Brian Urlacher, the Bears middle linebacker, is an example of the team’s rich tradition of excellence in that position.
Use commas to separate adjectives of equal rank.
Example:
Intimidated by the Chicago Bear defense, the Packers racked up a series of careless, foolish penalties in the second half.
Use commas with introductory phrases.
Example:
As Devin Hester ran the punt return back for a touchdown, the crowd went wild.
*If the sentences are not related, you must use a semi-colon. However, that edition of “Editing for Grammarphobes” is scheduled for later in the month, so I guess you are out of luck today.
