Thread:Project:Support desk/Is there any server side method to make specific templates only show to logged in users?

I ask because it would be useful to make templates that make announcements about the status of articles only viewable to logged in users. Some readers will have JavaScript disabled. As a historical wiki with some basic form of peer review (with Flagged Revisions) it might be useful to have a template indicating when claims are contested to notify reviewers that they should check the talk page before approving revisions.
