How do I post a message, add people, or attach files in a V5 discussion thread?

1. In the left sidebar, click "Discussion Management" to go to the discussion list. 2. In the list on the left, click the thread you want to view. To start a new one, click "New discussion" above the list. 3. To add someone, click "Add participant" in the "Discussion info" panel on the right. 4. In the "Type a message" field at the bottom of the center panel, type your content and click "Send". The message is posted in this thread. 5. If you need to attach a file, click the paperclip icon on the left of the input box to upload it.

Note: If you don't see the "People in this thread" section in the right panel, it means this thread currently has no contact person or email participant. This is normal.
