Free automated grammar correction

There are some places on the web where you don't want your writing to show up, such as The "Blog" of "Unnecessary Quotation Marks." But sometimes we all need help making sure our writing is flawless. What's a person to do? Help is at hand. Here is an article that lists some online sources for automated checking of your writing, including both spell checking and grammar correction. The article does mention that these tools are in addition to your own careful proofreading, and discusses some of the shortcomings of automated tools. For example, comma splices and dangling modifiers may not be identified. You should never assume a document that passes these tests will have no errors.
