There are a few ways to create links for site navigation and to feature links to other Internet sites:

• The main Navigation menu block in the sidebar (the one that displays your username as the title) can be configured via the menus configuration page. Some modules will automatically be added to the Navigation menu when enable. Otherwise, you can create, edit, and move around menu items from this configuration page. A couple of the menu items--create content and my account--are not as configurable as the rest of tmenu items.
• Many themes offer primary and secondary links that appear in the header of the page. These can be manually changed in the themes configuration section.
• Additional sidebar blocks can be created through the block configuration interface.

NOTE: Sometimes, it's not obvious as to the URL for a module's main page. Drupal builds module main page URL's from the module name as they are listed on the modules configuration page. For example, notice how the name is "forum"; the URL for the main forum page would then be http://example.com/forum.
