Multi-author blogging means inviting others to coauthor, or contribute articles, posts, pages, or other content to your blog. You can expand the offerings on your Web site or blog by using multi-author blogging because you can have several different people writing on different topics or offering different perspectives on the same topic. Many people use it to create a collaborative writing space on the Web, and WordPress doesn't limit you in the number of authors you can add to your blog.
Additionally, bloggers can invite other people to register as subscribers, who don't contribute content but are registered members of the blog, which can have benefits, too (for example, some sites make content available to registered users only).
This chapter takes you through the steps of adding users to your blog, takes the mystery out of the different user roles and capabilities, and gives you some tools for managing a multi-author Web site by using WordPress.
