==Features==
The the title and talent ''pages'' of IMDb are accessible to all users, but only registered and logged-in users can submit new material and suggest edits to existing entries. Most of the site's data has been provided by these volunteers. Registered users with a proven track record are able to add and make corrections to cast lists, credits, and some other data points. However, the addition and removal of images, and alterations to titles, cast and crew names, character names, and plot summaries are subject to an approval process; this usually takes between 24 and 72 hours.
 
On October 2, 2007,{{citation needed|date=October 2013}} character filmographies were added. Character entries are created from character listings in the main filmography database, and as such do not need any additional verification by IMDb staff. They have already been verified when they are added to the main filmography.

The IMDb Top 250 is a [[List (information)|list]] of the top rated 250 films, based on ratings by the registered users of the website using the methods described. {{As of|2023|09|05}}, ''[[The Shawshank Redemption]]'', directed by [[Frank Darabont]], is No. 1 on the list, and has been since 2008.<ref name="AVFilm14">{{cite web | first=A.A. |last=Dowd | url =https://film.avclub.com/escape-is-the-unlikely-link-between-the-shawshank-redem-1798271320 | title =Escape is the unlikely link between The Shawshank Redemption and Natural Born Killers | date =August 19, 2014 | access-date = September 23, 2017 | website= [[The A.V.

The number of votes a registered user would have to make to be considered as a user who votes regularly has been kept secret. IMDb has stated that to maintain the effectiveness of the Top&nbsp;250 list they "''deliberately do not disclose the criteria used for a person to be counted as a regular voter''".<ref>{{cite web|url=https://www.imdb.com/help/search?domain=helpdesk_faq&index=1&file=notintop250|title=The user votes average on film or show ''X'' is 9.4, so it should appear in your Top&nbsp;top 250 Movies or TV list, yet it doesn't.

Beginning in 2001, the Internet Movie Database also maintained message boards for every title (excepting, as of 2013, TV episodes, which used the same message board for the whole series) and name entry, along with over 140 main boards. To post on the message boards a user needed to "authenticate" their account via cell phone, credit card, or by having been a recent customer of the parent company [[Amazon.com]]. Message boards expanded in recent years. The Soapbox started in 1999 as a general message board meant for debates on any subjects. The Politics board started in 2007 was a message board to discuss politics, news events, and current affairs, as well as history and economics.{{citation needed|date=March 2017}}
 
By February 20, 2017, all the message boards and their content were permanently removed. According to the website, the decision was made because the boards were "no longer providing a positive, useful experience for the vast majority of our more than 250&nbsp;million monthly users worldwide".<ref>{{cite web|url=https://www.theverge.com/2017/2/3/14501390/imdb-closing-user-forums-comments|title=IMDb is closing its message boards|last=Liptak|first=Andrew|date=February 3, 2017|website=[[The Verge]]|access-date=February 15, 2022|archive-date=November 12, 2020|archive-url=https://web.archive.org/web/20201112041601/http://www.theverge.com/2017/2/3/14501390/imdb-closing-user-forums-comments|url-status=live}}</ref> Others have mentioned its susceptibility to [[Troll (slang)|trolling]] and disagreeable behavior.<ref>{{cite web|url=https://techcrunch.com/2017/02/03/one-of-the-worst-comments-sections-on-the-internet-is-shutting-down/ |first1=Sarah |last1=Perez |website=TechCrunch |title=One of the worst comment sections on the Internet is shutting down|date=February 3, 2017|access-date=April 10, 2019|archive-date=October 20, 2020|archive-url=https://web.archive.org/web/20201020044636/https://techcrunch.com/2017/02/03/one-of-the-worst-comments-sections-on-the-internet-is-shutting-down/|url-status=live}}</ref><ref>{{cite web|url=https://www.bostonglobe.com/arts/movies/2017/03/09/internet-movie-database-robust-community-goes-boards/QI8mDhM15L2iQzTTf5K0JJ/story.html |url-access=subscription |date=March 9, 2017 |first1=Ty |last1=Burr |title=Should IMDB have preserved its comment boards – flame wars and all?|website=[[The Boston Globe]]|access-date=April 10, 2019|archive-date=November 12, 2020|archive-url=https://web.archive.org/web/20201112003811/https://www.bostonglobe.com/arts/movies/2017/03/09/internet-movie-database-robust-community-goes-boards/QI8mDhM15L2iQzTTf5K0JJ/story.html|url-status=live}}</ref><ref>{{cite web|url=https://www.theringer.com/2017/2/21/16043918/imdb-message-board-shuts-down-80b632d6ab79 |first1= Claire |last1=McNear |website=The Ringer |title=Not Even IMDB Is Safe From Trolls|date=February 21, 2017|access-date=April 10, 2019|archive-date=November 12, 2020|archive-url=https://web.archive.org/web/20201112043304/https://www.theringer.com/2017/2/21/16043918/imdb-message-board-shuts-down-80b632d6ab79|url-status=live}}</ref><!-- archive version containing the actual announcement needed --> Needham also mentioned in a post some months earlier that the boards received less income from ads, and that their members only made up a very small part of the website's visitors.
