This is as you know a stock account. My main profile can be found here:
aliencraft.deviantart.com/ - The main rule is that you give proper credit. It's annoying when you provide someone with content and they forget to mention you when they rake in the fame and get praised.
Just a simple link back to my stock account or mention of my stock account name: ~deltastock would suffice. You can use them anywhere you wish, however you wish.
Regards,
