In the archive of this mailing list I found the following:
>CFF is a newsletter published by the Nederlandse Kubus Club NKC (Dutch
>Cubists Club). It appears a bit irregular, but a few times a year.
>Yearly membership fee is now NLG 25.- (Dutch Guilders) which amounts to
>approximately $ 15.-. Institutional membership is also possible.
>Information is available from the editor Gerald Maurice
Unfortunaty, the abovementioned editor didn't respond to my email.
Does anyone know whether CFF still exists? Who is the current editor?
