Content rules are an advanced function of the web system that allow you to set automatic actions to occur whenever a user does something specific. For instance, you can set up email alerts to be sent every time an item is published on your site.
The version history of items such as pages, images, news, etc provides a list of all the edits/changes made to such items. Each time changes are made to an item, a new version is saved. These various versions will then be listed under "History".
Working Copy allows you to work on a parallel copy of a page so that edits can be made at leisure while the original version is still live to site visitors.
Portlets are dynamically generated (or static) content views that can be displayed in special areas of the site layout. There are two basic kinds: fixed-column portlets and content well portlets.
jQuery Tools is a collection of user interface plugins that allow you to achieve effects like tabbed content, lightbox-style overlays, and tooltips. These effects are already built into the web system, but they're implemented through the editing of page HTML.
Need another calendar? One specifically for students? Or a web-based Intranet calendar for your department? Add one by changing the settings of a folder.
