If I had to pick just one that has totally changed my poser functionality, I would say MartinC's Mac Converter (for me anyhow). It has saved me from making several hundred new thumbnails by hand. Thanks Martin! Koz's hair, Sam3D's freebies, Steveshanks tutorials.. there are just way too many top notch 3D freebies to pick. They are all great in different ways, serving different needs. -Adam
