Article comments is a feature that allows users to leave comments at the foot of an article, usually for feedback on the article or discussion on its topic. It is sometimes used as an alternative for talk pages. Some wikis use both talk pages and article comments and some only use one. Newly created wikis have article comments enabled by default and contain no tabs for talk pages.
How to disableEdit
Sysops can disable this feature through Wikia Labs (at Special:Wikialabs) - previously, this required contacting staff to change.
Alternatively, CSS can be used to hide article comments. This only hides them, it does not remove them outright, nor does it restore talk page links, so spambots could still post spam comments.
