How do I send a message in a V5 discussion thread? Can I reply by email?

1. Enter a keyword in "Search Topic Name" on the left, then select the discussion thread you want to open. 2. Check the participants on the right to confirm who is in the discussion, then enter your message in "Enter Message" at the bottom. To add an attachment, click the paperclip icon. 3. Click "Send to…" to check the recipients, and note the visibility notice. If it says "Only colleagues can see this", confirm that this matches your intended recipients and visibility before clicking "Send". 4. To reply by email, first check whether the "Reply by Email" button is available. In the current screen, the button is grayed out and cannot be used at this time.
