Best thing to do is look at some of the first things submitted to the free stuff sections. There really is a ton of stuff for Posette and some for Dork, but you have to look at the "beginning"... which is to say, go the the "end" of the freestuff section and work your way forward. Do the same at some of the other sites (3D-Commune, Ghastly's site, etc.) I think you'll be pleasantly surprised at the quality and quantity of P4 items available.
