Use the "Tag Cloud" tool to create a visual depiction of all the keywords used in your project. A tag cloud gives an immediate impression of what the most important ideas are for the project as well as a set of links to related content. Only project administrators can add this feature.
To add a tag cloud, an administrator must click on "Edit Home Page" in the Toolbox. From there, click on the cog in the upper left corner of one of the display regions of the template and add a content pane in which to display the tag cloud. The "Tag Cloud" content pane is under "More Tools."
