Each member has a comment permission on every site. Use it when someone should be able to discuss feedback with your team but shouldn't reply to the people who submitted it, for example a contractor or a developer who isn't customer-facing.
Permission options
All comments: the member can post public replies to reporters and add internal notes.
Internal notes only: the member can add internal notes visible only to your team, and can't post replies that reporters see.
Change a member's permission
Go to the Sites page.
Click the ... menu on the site's card and select Manage Members.
Find the member and open their permission dropdown.
Select All comments or Internal notes only.
The change saves automatically and a "Changes saved" message appears. It applies to this site only. Set it on each site where it's needed.
