Mailing lists are now available.
cpplint-users - This is a general purpose mailing list for getting help with C++ lint
cpplint-announce - This is an administrator-only list relating to announcements of future updates and releases of C++ lint
I've opened up a very early alpha of my C++ lint for comments and suggestions. Please remember that this is definately not a full-functioning checker. If you have any useful suggestions, please post them in the message boards.
