Like a simple chat room, or a forum reduced to a single thread. Commonly placed on the main page of a website.

Many {{webcomics}} don't have a large enough community to support a full-size, separate message board. A ShoutBox is one way to provide easy, highly-visible interactivity.

See also TheRant.

!!Examples:

* ''AlienDice' uses one for comics and newsposts, even though it does have a forum.
* ''BeyondReality'' has bot one of these and a forum.
* ''Webcomic/CatNine'' uses Chatango and found on most pages.
* ''Webcomic/DreamCatcher'' uses one.
* Users of {{deviantART}} who subscribe have the option to put a shoutbox with any journal they post.
* ''[[http://www.graphicsmash.com/comics/brathalla.php Brat-halla]]'' has embedded a single, blog-powered comment thread for a similar effect.
* [[http://www.myshoutbox.com/ MYSHOUTBOX]] (seriously, they put it in all caps like that) is used by ''[[http://www.juathuur.spiderforest.com/ Juathuur]]''.
* Tom Siddell of ''Webcomic/GunnerkriggCourt'' used the home-encoded comment thread for PaintingTheMedium during the interim comic ''Webcomic/CityFace'': instead of displaying RealLife reader comments, it displayed comments from the AnimatedActors and other in-universe characters reading the [[ShowWithinAShow comic within the comic]]. They're archived [[http://gunnerkrigg.wikia.com/wiki/City_Face_comments here]].
* BearAndKitten had a very avid fanbase that actively posted in their shoutbox. Oddly enough, even though the webcomic hasn't update in almost a year now, the fans still post in the shoutbox because they actually became a close knit group of friends. Seemingly forgetting that they even came to the website for the comic.
** Currently the site is down, but the shoutbox is still accessible via internet archive.
* Conversely, BizarreUprising's shoutbox has consisted primarily of complaints of TheyChangedItNowItSucks vis-a-vis the TimeSkip.
* ''PlanetZebeth'' uses one as well.
* ''Webcomic/{{The Monster and The Girl}}'' has a shoutbox arranged that a message on one comic page is seen on all the comic pages.
