There are two main ways to navigate through the forum application.
On top and bottom of all pages is a "breadcrumb" line. These links show where in the community you are reading and give you the option to click up or down the structure of the community. Within each breadcrumb line are also icons to open up options within each level of the site. Each icon will open up direct links to tools like search or other forums and categories within the Forum application.
A second navigation tool is the "Go" button built into the top left side of each page.
Use the "Go" button to navigate directly to your Personal Zone, Forums or Chat if enabled.
