Community
Wiki
The Trac-powered wiki contains a collection of useful tips and tricks. It also contains a list of sample nanoc sites (including this very site) which you can check out to improve your nanoc-fu.
Discussion Groups
nanoc has a discussion group hosted at Google Groups. There probably is no better place to ask for help if you’re having trouble. In addition to that, there is a Spanish discussion group for those who prefer to speak Spanish. (I won’t be able to join the discussion there though, as I don’t speak Spanish.)
IRC Channel
There is a nanoc IRC channel named #nanoc at freenode. Feel free to drop to get support or discuss development.
