Actually, there are more pages than that for Renderosity freebies (if you're going to count ShareCG's home page).

• You have the Renderosity home page.
• Then, you have to log in or register (unless you're already logged in).
• Then you have to find and click the freebies link from the menu.

Getting to a list of Poser-only freebies (see below) requires even more work and fiddling around since it's not in the main menu:
