i understand copyright is an automatic protection, but would registering a copyright with an official body, such as a (copyright registration service) give the copyright owner a stronger case of evidence should there be a dispute over authorship??? i know in the U.S. its a requirement to register your copyright with the (U.S. copyright office) but i dont reside in the U.S. but in europe..
example, additional witnesses, hence the (Copyright registration office) to aurthenticate your ownership of copyright, should there be a dispute...
or is just mailing the copyright to yourself through the national post just as good???
