Inviting other bloggers and writers to become co-authors is one great way to expand one’s blog. Assuming the recruiting of writers part is being taken care of, the next big problem you could be facing is management. Managing multiple authors for a blog is never an easy task. It’s often a challenge to keep co-authors in control, getting them to write quality content on schedule, making sure they did not miss anything before hitting the publish button, etc. Also sometimes you might also want to give different authors different level of accessibility and controls, depending on their performances.
