Don't know where you're reading your copyright law, Mr. Eclipse, but you're very wrong. Nothing needs to be registered for copyright to be enforced. All Kickstart versions are copyrighted from their moment of inception.
In the U.K:
"Copyright is an automatic right and arises whenever an individual or company creates a work. To qualify, a work should be regarded as original, and exhibits a degree of labour, skill or judgement."
Not only is registration unnecessary, but there is nowhere in the U.K to register with regardless.
In the U.S:
"While copyright in the United States automatically attaches upon the creation of an original work of authorship, registration with the Copyright Office puts a copyright holder in a better position if litigation arises over the copyright. "
Registration is not necessary, and is purely for the paranoid to show proof of creation.
