Community folders organize communities hierarchically within the PAF. Visitors to the portal site see the Community name, rather than the name of the community folder. Each community folder contains both a name and a Web-Friendly URL. The Web-Friendly URL is used to generate the URL for the Community pages. Consequently, the Web-Friendly URL can contain only alphanumeric characters. Spaces and symbol characters in the Web-Friendly URL are removed, because they would otherwise cause the page to generate an error.
