Infoboxes and user style
Logged-in users can use user CSS to hide infoboxes in their own browsers.
To hide all infoboxes, add the following to Special:MyPage/common.css (for all skins, or Special:MyPage/skin.css for just the current skin), on a line by itself: <source lang="css">.infobox { display: none; }</source>
