Nice work, Dan!

One of the things that I dislike about using capybara/rspec to write feature specs is that you loose the Given/When/Then format. At least is not obvious to my eyes.

@cored I haven't had much opportunity to try it - but there is a simple system by the author of capybara called turnip that gives those options.
