It's time I addressed the subject of the many PSP groups on Yahoo and MSN. Representatives from these contact me on a fairly regular basis asking for permission to use my pieces to create signature tags and other graphics.
The simple answer for now is yes, you can use my images as long as you include a link to my page here on dA, there is no commercial benefit of any kind and as long as you don't add a copyright symbol of your own - if you want to copyright work create it from scratch!
These are my only requirements at the moment. Please note however, I may change my mind on this in the future.
