There is no problem posting a link to the NewTek site, but I guess there is a problem posting a link to a page that has nothing but free video tutorials (that happens to be on the NewTek site).
I'm saying this since once someone created a simple, short, sped up video tutorial showing how he models ears. It was completely free and couldn't even compare to what this site offers. But the link was edited out (I think by Kevin), and the user left.
Maybe SimplyLightWave isn't so strict as it used to be but that happened.
