People, "license-free" just means the default copyright law applies, which means nobody can copy or share the work. It's not the same as public domain. If you want your work to be Free, just choose a common FOSS license.

(This is generally true around the world. Only an handful of countries haven't signed one of the various copyright treaties that require automatic protection.)

many thanks for your comment, I didn't know about that :)) Now I got it modified to MIT License. Please let me know if you know of a more open license that I can use :))
