While you're there, check out some of the great advice and information for working wordsmiths on the blog, including a few from yours truly:
The AP released a handful of of updates to its stylebook early this week. In "Associated Press Updates Stylebook," I give a quick overview of what you need to know if you follow AP style.
In "A Comma Problem among Editors," I write about a common point of disagreement among editors — the placement or absence of commas that might not strictly be necessary.

In "Singular or Plural, the Writing's on the Wall," I talk about the word graffiti and it's little-used singular form, graffito, with some advice on how and when to pair them with the right verbs.
