your missing a few points.

not everyone comes to rendo. there are many freebies that don't get posted here unless someone posts them in the forums.

Japanese sites. all of Kazboro's hairs. free software. etc

put it this way. Microsoft offer free programs that ppl here can use. you want them to put their stuff through renderosity testing?

also Poser Python Scripts that have been written by kind ppl here to help others out. want them tested before they can be posted? (they are freestuff..)
