Registered users who are authorized to enter content can do so using the 'Create content' menu link in the menu block. Content can be entered in a variety of formats. The filter module allows administrators to configure text input formats for the site. For example, an administrator may want a filter to strip out malicious HTML from user's comments. Administrators may also want to make URLs linkable even if they are only entered in an unlinked format.

Users can choose between the available input formats when creating or editing content. Administrators can configure which input formats are available to which user roles, as well as choose a default input format. Administrators can also create new input formats. Each input format can be configured to use a selection of filters.

Information for administrators regarding permissions for content entry can be found here.
