There are three primary content types--blogs, forum topics, and knowledgebase wiki posts. Content navigation for all three types is mainly through TAGS or Categories. Click on Blogs in the Site Navigation menu on the left side of the webpage. On Blogs page, right hand side, is the TAG navigation menu. Click on a Category and you go to all posts in that Category. The same generally applies to Knowledgebase Wiki posts--click on Knowledgebase Wiki in the Site Navigation and go to the Wiki homepage. On the right side are the knowledgebase categories. The Knowledgebase materials are also divided into Books." The Books are simply a category structure. In the center panel of the Wiki homepage the primary Book Tags/Categories are listed. Click on a subject and you go to all the materials in that Tag/Category. The Book structure has the added feature, at the bottom of each wiki page, of providing a navigation link to the wiki articles before and after the displayed wiki post. Rather than Categories/Tags, Forum content is divided into different Forums that correspond to categories. You click on Forums in the Site Navigation Menu and go to the Forum listings. Click on the subject you are interested in and find topics of interest. Finally, the site allows you to use the Search function in the primary menu tabs at the top of the page. You can conduct a general search in all content, search by content type, or search for material within a particular blog, forum, or knolwedgebase Category. A separate help topic has been posted on using the Search function.
