About Ribbot

Standard online forums often lead to low quality discussions. Sites like Hacker News, Reddit, StackOverflow, and 37Signals Answers have pioneered a new format for forums that leads to higher quality content. They are characterized by a number of features including post ranking, user reputation, crowd sourcing, and threaded discussions.

Ribbot seeks to allow any company or online community to setup a similar forum and build a high quality community online.

• Be sure to run the test suite to make sure nothing broke, and please add a new test for new functionality (especially high level request/integration specs)
• You can keep tests running continually in the background while developing with guard (this is preferred) or one off using rspec spec
