nanoc has a discussion group hosted at Google Groups. There probably is no better place to ask for help if you’re having trouble.
There is a nanoc IRC channel named #nanoc at freenode. Feel free to drop to get support or discuss development. I’m not always around, so stick around for a while or send a message to the nanoc discussion group instead (see above).
The nanoc wiki at GitHub contains a collection of useful tips and tricks, sample nanoc sites (including this very site) which you can check out to improve your nanoc-fu, third-party extensions and more. It is also the place where development-related brainstorming goes on.
