Here’s what Squarespace says within their site management application about Creative Commons:
We’ve integrated a utility that lets you generate Creative Commons licenses for your site. A Creative Commons License is an excellent alternative to default copyright, and lets you retain very specific rights over the works you place on your website. The process for generating a license is one step, and free. Takes about 30 seconds. We recommend giving them a look!
Well said! We recommend giving Squarespace and other CC-enabled applications a look.
