You seem to be picky about the wording in my last email. Nonetheless I 
can confirm you that the C-FSL license works as intended for the 
original authors. They are safe to use the patches of other people also 
and especially if they want to relicense their work later on. This is 
done by implicit consent of each contributor.

The original authors are effective copyright holder of the whole work 
which means that they can relicense. Of course everyone has a copyright 
on his own contribution but by using C-FSL contributors give the right 
to relicense to the original authors.

What I mean here by publishing another time under C-FSL is appointing 
their own set of original authors.
