Rules
In a nutshell,
None.
This is a non-restricted stock site which means (for me anyway):

I don't need credit but a link back would help people find the image (if they want to use it too).

You don't need to inform me if you use it.
If you would like to show me your work, please leave me a message. I'm always thrilled to see what people manage to create.

You can use my stock anywhere and however you want in your art work.
That includes:
-dA prints ( I grant full permission etc, etc)
-Any other commercial or non-commercial project.
-You are not obliged to change it to use it. 
BUT please, please don't redistribute as a resource in raw form and then claim it or sell it.

Premades:
Yes. And I would love to see them too!
If you make free premades for dA with any of my stock, I would ideally hope to see other dA members using it, without restriction BUT I leave it up to you.
*If you are selling your premades then, ofcourse, you can do whatever you need to.

Everything is stated here, so you should have no issue getting any print permission. If you have any problem making prints through dA and need some sort of authorization, note me on my main account =jantar-mantar

Hope you can find a use for something here....

PS: Though not required, I would LOVE to see what you create .People have been coming up with some amazing art!

Thanks
