Hi guys,

let's not make too much out of the license problem right now. We are
working to fixing up the license on the ubuntu-site. When that is done
we can go and talk to the guy and *ask* why he licensed it like this.
It might be he just has not thought about it.
It is nice people write about Ubuntu and it is really quite nice.
Let's not flame him. If we can solve all this in a friendly way then
that is much preferable.

greets all from Barcelona,
