Hey DN, I'm the co-founder of Binded. We created Binded for designers, photographers and artists. Feedback on the product is greatly appreciated! :)
Very cool idea, and hopefully incredibly useful for photographers looking to copyright their photos.
Two quick notes:
The DN link goes to the copyright page (which is great), but your homepage doesn't appear to link there. You should have a button under the "How it works" section that leads to the copyright page.
When you said you don't make any money from the registration I immediately because suspicious because obviously you need to make money somehow... typically. I ended up finding your answer to that question on the FAQ page, but it might not hurt to add a little "How are we funded?" to quickly direct people with the same question I had.
Nice site, great idea. Hope things work out well!
