I signed my w-9, uploaded like 15 models, and then never heard anything back, my models also didn't show up in the marketplace. Anyone know why? Or what I can do?

Hmm, indeed, your store shows 14 content items uploaded but none listed.

It took me a while but I finally figured it out. There was another step to publish which I had not done. Thanks
