A few quick thoughts...

1. An "Install Products" choice in the File menu which puts all purchased products in the Purchased section of Poser. Simple.

2. All free products should be inspected by staff prior to being put in the store, or they should be shared elsewhere. Reliable.

3. Now that Rendo owns Poser, how about a Poser only store, perhaps on posersoftware.com? Clear.

Simple, reliable, clear.

A Poser only place to shop, one simple way to install purchases, all offerings verified by experts.

No need for tutorials, or threads like this.
