Because you have created this workspace yourself, you are automatically the moderator and have free access. This status is required for carrying out administrative activities.
For example, you can change the workspace settings (tool icon in the CommSy-bar) or allow access to new members.
You can also assign moderator status to other workspace members, e.g. to tutors, student assistants, or participants in a study group.
To do this, click on settings in the CommSy-bar at the top of your project workspace and select the "User-IDs" tab. You can change the status of one or more users by clicking on the box next to the name and selecting the appropriate action from the drop-down menu.
