The Forums API allows you to create and manage Forums (AKA Disqus Sites or Discussions).
To use the Choreos in this bundle you need a Disqus account, which you can sign up for here. You will also need to register an application to obtain a PublicKey and SecretKey. All Choreos require a PublicKey. Some Choreos will also require authentication using an OAuth 2.0 AccessToken. For applications that simply need to authenticate you as the account owner, Disqus provides a special access token for this purpose on your application's details page.
