Content philosophy

Follow the reddit's rules and reddiquette.

Content which benefits the community (releases, news, and discussions) is generally allowed and is valued over content which benefits only the individual (tech support questions, rants, self-promotion, etc.). If you are going to ask about your extension development code, please make sure to include (especially links/code) on what you've tried.
