They have modify and copy permissions, so you can use them to add to your ao, poseball and everything you want and change the name for an easy search in your inventory.
They have priority 4 for no typing animation and some have the neck free, so you can make the avatar to look wherever you want.
You can also try them and purchase the poses and animations separately from a vendor in the store.
