Ron,
Not everyone has the time to categorize each and every item in their poser folder. I know I don't with two kids and two businesses.

3D Arena is set up very well. A comparison to Renderosity in size and content isn't very fair since they are so new in comparison. They are better organized though.

How difficult would a checkbox be to add? I'm not suggesting retroactive, that would be horrendous.
OR, until/when Renderosity can organize the free section better, the user could add themselves something like "per/com" for personal or commercial or just "per" or "com". I plan to with my next freestuff upload.
