If you have connected your WordPress site to CoSchedule, Owners, Managers, and Admins are able to associate WordPress author accounts to your CoSchedule team member accounts. Associating a CoSchedule team member with their WordPress author account allows for smarter notifications. However, you do not need to have every WordPress author associated with a CoSchedule team member. It is possible to have many authors in WordPress but only a few team members in CoSchedule.
To associate WordPress Authors to your CoSchedule account, go to Settings > Integrations > WordPress > Site Name page.
