[Piotr Banski]

Dear CSC,

This is to say thank you and goodbye to Claus Povlsen, Ineke Schuurman, 
and Peteris Paikens, who, for independent reasons, are no longer members 
of our committee. Claus, Ineke, Peteris: all the best in your future 
endeavours and see you around!

I will update the mailing list membership in the coming days.

Best regards,

   Piotr
