PBworks has traditionally been focused on being simpler and easier to use than most other wiki platforms. It offers two levels of access, a free version that has most of the functionality needed by individuals or small workgroups, and a paid version that offers more functionality. PBworks also supplies paying customers with templates and wikis pre-configured for certain industry applications, such as its Legal and Campus editions. (This book was written, edited, reviewed, and published using PBworks.)
