OAuth implemented

Omniauth has been implemented and working with Facebook and Twitter. However, this implementation is unable to link the Twitter account to an existing account.
I created a Facebook and Twitter application to get this to work, but I have not included the figaro config file since these are supposed to be secret.

Adding other OAuth providers should be as simple as adding their gem, and initializing them in devise.rb
There is a omniauth-meetup gem.
