Like 10.1/PPC, Mandrakelinux 10.2/PPC is not an official Mandrakesoft product but a volunteer effort. If you want to help with releases, PPC-specific problems with packages, or testing, subscribe to the cooker/ppc mailing list and/or join us on IRC, in #mandrake-ppc on Freenode. Both places can also be used for support questions.
