A guest will be able to view, edit, and respond to the thread they've been added to, but they won’t be able to access any other threads in the space that thread is in.
You can also add them directly as a member to the space to give them access to all the threads in the space.
To add a guest to a thread:
- Go to the thread
- Click the Add Someone button the right-side navigation
- Add them to the thread using their name or email address
You can view all the guests in a space in the Directly added section of the thread.
