The rules to follow are

You don't need to ask permission to use

You do have to credit me in your artist comment and put a link back to my stock ( also when you use the psd files of the brushes or the abr brushes)

Don't make photoshopbrushes of my pspbrushes, and put them up as your own.

Don't make brushes of my stock, if you don't bother to give a proper credit.

You may NOT use them outside DeviantArt, Unless you NOTE me and ASK permission. I usually grant permission if you ask

You Have to NOTE me or leave a comment under the photo or brushes you have used, so that i can take a look and fav it

No need to ask a print permission for DA Artists ,

HOWEVER outside DA you still need to ask permission before you put it up as print and to use my stock
