ooc 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 an ooc IRC channel named #ooc-lang at Freenode. Feel free to drop by to discuss development, or if you need support. There is not always someone available, though, so feel free to send a message to the ooc-lang discussion group instead (see above).
The rock wiki at GitHub is the place to add your ooc tips and tricks, sample code which you can check out to improve your ooc-fu, third-party tools and more. It is also a good place to discuss development-related brainstorming, such as proposed features.
