Through the "Project Admin" Page, you are shown with links to different task: Admin, User Permissions, Edit
Public Info, Project History, VHOSTS, Post Jobs, Edit Jobs, Edit MultiMedia Data, Database Admin. In particular,
this is where you can
- Enable or disable services for your project
- Add users to your project and give them roles. Roles control scm access, forum access, etc.
- Roles are not always very correctly implemented with respect to their descriptions, in particular for private projects. You should experiment before relying on them.
