Project Settings
Project Members
Here you can add members to your projects (using the “Add a new member...” button).
You can also change user roles. Here are the roles:
admin
This is a person who can change anything about the project.member
This is a person who can add and vote on glosses, but can't change project settings.disabled
If some member behaves badly, you can disable them. Their votes will no longer count.
Power user
This is for users who can be trusted to do dangerous things. See this page for more details.
