Every project has a community.
The community of your project includes everyone who is involved in your project.
When you create a project the following roles are automatically generated.
You can add as many additional roles as you like.
Every role has as set of privileges which entitle the holders of a role to create, amend or delete project relevant information. This is an easy and safe way to grant access to project information and tools.
In the privileges settings you can define which role gets which privileges.
Once you've defined the roles you can add member to your community and assign roles to those members.
