By adding a thread, you can provide a place for communication by topic and can easily organize the information.
You can add a thread only when "Enable multiple threads. Note: This setting cannot be reverted." option is enabled in a space.

All users who have access to the space can add threads. To add a tread, follow the steps below.

1. From the Space Portal page to which you add a thread, click the plus sign on the right side of "Threads".
2. Enter the thread name and the body text, and click "Save".
