You're not actually allowed to: >Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. From wiki though: >According to the GPL FAQ, anyone can make a new license using a modified version of the GPL as long as they use a different name for the license, do not mention "GNU", and remove the preamble, though the preamble can be used in a modified license if permission to use it is obtained from the Free Software Foundation (FSF).[60]
