Hi folks,

is it allowed to make changes in the GPL down the GPL-Copyright preamble in
a licence-file?

Isn't it so, that the GPL guarantees us, that all under this preamble has to
be free for all?

Now I want to change the properties so, that anyone who wants to copy,
distribute oder sell my software, has to ask me before.

Can I do so, or is this not allowed by GPL?
