Things you need to know:
Can I derive and make mine derivable?
Yes, as long as you are deriving from my product. I will have any of my digital content removed via DMCA if not used in it's original derivation chain.

Can I use your icon for my derive?
Of course, though I don't see why you'd want my name on your catalog.

Can I have the original files to upload to the pose maker?
NO. I don't release any content other than through IMVU's Creator Program.
