There are 4 user roles or access levels on BlogIn that define what each user can do on the blog:
1) Reader - can only read posts and comments created by other users
2) Commenter - can create comments on posts but can not create posts
3) Writer - can create posts and comments
4) Administrator - can access and control everything, which means creating new posts and comments, approving and editing all posts and comments, managing post categories, creating pages and managing user teams, inviting new team members, customizing blog account (company logo, custom domain, open email domain..)
Blog Administrators can change each user's user role at any time and can also define a user role for each user when inviting new users to join the blog.
