# Moodle Instructions for Teaching Staff: External Participants

This source provides a step-by-step guide for instructors at the Universität Greifswald on how to configure external access for BigBlueButton (BBB) activities within a Moodle course.

## Key Technical Details

### External Access Constraints
- **Limited Scope**: External participants are strictly limited to BigBlueButton activities. They cannot access any other course materials, files, or Moodle components.
- **Account Requirement**: Access to any other part of the course requires a [[zentraler-nutzeraccount]].

### Configuration Workflow for BBB Guest Access
1. **Enable Editing**: Activate the editing mode in the Moodle course.
2. **Add Activity**: Create a "BigBlueButton" activity in the desired course section.
3. **Enable Guest Access**: Check the "Guest Access" (Gastzugang) box in the activity settings.
4. **Waiting Room**: Optionally enable moderator confirmation to implement a waiting room function.
5. **Distribution**: Use the "Add Guests" (Gäste hinzufügen) button to retrieve the meeting link and password, or enter email addresses to send these credentials automatically.

### Limitations
- **Password Immutability**: The automatically generated guest password cannot be changed after the activity is created. To change the password, a new BBB activity must be created and new credentials distributed.

## Support
Technical issues are handled by the [[universitatsrechenzentrum-urz]] via the [[groupware]] ticket system or the URZ hotline (ext. 1420).
