Content issues can include lexical, syntactic or semantics errors; factual errors; broken links; missing information; accessibility; copyright; compliance or other legal issues.
Errors associated with existing or missing content on a website should be reported to the site editor.
The site editor will normally be someone in the department or group that the site is for. In some cases this person will have the role of webmaster for the department or group. Many sites provide a feedback form that can be used to reach the site editor. Local IT staff or your department webmaster may also be able to identify the site editor for you.
