The Filter module allows administrators to configure text formats. Text formats change how HTML tags and other text will be <em>processed and displayed</em> in the site. They are used to transform text, and also help to defend your web site against potentially damaging input from malicious users. Visual text editors can be associated with text formats by using the <a href=":editor_help">Text Editor module</a>. For more information, see the <a href=":filter_do">online documentation for the Filter module</a>.
