We have 3 users roles in the platform
Here is a list of what they can do:
Inviting users is straightforward, simply head to the project you want to invite the users to and click on the 'Add to a project' button in the bottom left corner. You can invite one or many users at the same time, by simply adding their email addresses and assigning roles to them. Note that you can assign permission up to the same level as your role.
