Creative Commons have announced the launch of the CC+ (aka CC Plus) and CC0 (aka CC Zero) programs. These are major additions to the Creative Commons array of legal tools.

In a nutshell, CC+ is a protocol to enable a simple way for users to get rights beyond those granted by a CC license.  Meanwhile, CC0 is a protocol that enables people to either assert that a work has no legal restrictions attached to it or waive any rights associated with a work so it has no legal restrictions attached to it. The program also provides an easy way to sign these assertions or waivers.
