I often look for resources for our authors so they may spread the word about their books. One online source is Freelance writing jobs at freelancewriting.com.
There are plenty of articles to guide the new or even the seasoned writer. If you are an author, you need to get additional exposure and online writing is a great way to do it. I know I harp on this, but it's true. The bonus? Sometimes you'll even get paid for what you write.
