Not sure if this is right place for jobs post?
Came across really nice London UK website, for retired people to pass on their knowledge:
And they're looking for freelance Rails dev:
enthusiastic dev with experience working on social applications, especially if you’ve used Activemerchant, CanCan and Devise. Experience building well tested apps using Cucumber/Capybara would be very useful. As we develop the Amazings platform we’ll want to integrate more social features using Facebook and Twitter (including user authentication with devise/omniauth)
Hope that's of use to someone 
cheers, Jake
