WikiCancel is the most current subscription, contract, and account cancellation guide. This Wiki lists the steps to delete your online accounts, such as Facebook, LinkedIn, and Twitter, cancel contracts with companies, such as Sprint, Comcast, and LA Fitness, and unsubscribe from emails from sites like Groupon and LivingSocial.
WikiCancel's goal is to make cancelling a subscription, contract, or account easier by increasing the accessibility of this information. Check out the Help page to see how you can add a company, or the Project page for more information about WikiCancel. You can use the search box to find companies, and if you do not find a company you can create the page!
