For general browsing I suggest using the tabs on the navigation bar at the top of the page, this will allow you to move around the site as you wish and these tabs appear on all pages allowing you to jump back and forth and hither and thither as you like.
For more specific areas of interest I would suggest using the “Main Categories” lists on the left sidebar ( below the “Sister Sites” links ). This is a dropdown expanding menu that allows you to select areas of specific interest. For example you can chose to view news on all aircraft kits, or you could choose to view news only on 1/72 scale aircraft kits. This allows you to filter out what doesn’t interest you.
