Memory Alpha articles are never truly finished. Even featured articles, examples of Memory Alpha's best work, will over time have to undergo revisions to keep them up to date. Therefore, it's important to review the featured articles from time to time to ensure that these revisions have not only happened, but have maintained the quality expected of a featured article.
If you would like to help by starting a review, a good place to start is featured articles more than five years old, which are listed here. Please make sure you are familiar with the review policy before proceeding, though. For past reviews, please see the archive.
Reviews can be started by beginning a new discussion on this page. If you think that a featured articles' status should be upheld, add it to the "Uphold" section. If you think that the article should be removed from the feature article list, it should be added to the "Remove" section. Either way, be sure to state the reason(s) why you think the article should be reviewed. Reviews should display, and have a link to, the blurb used on the portals, by adding {{Blurb|ARTICLE}} before the discussion.
Sample format:
=== ARTICLE === {{Blurb|ARTICLE}} <reasoning> - <signature>
Once this is done, a notice that the article's status is being reviewed should be added to the article in question by inserting {{far}} at the top of the page, above any other templates except the article type template.
When you are commenting on a review, please take the time to read the entire article before you decide whether to Support or Oppose the motion. When supporting or opposing an article, please use a bullet point (by adding a * before your comment) without any indent so these will be easy to find later. General comments should be indented as usual, and, as always, please sign your nominations and comments with "~~~~".
