Twitter Commenters is a plugin for Movable Type that enables commenters to sign-in and comment on your blog using their Twitter account.

Twitter comment authentication works like other auth methods in MT -- once you have installed the plugin you can enable Twitter as one of the auth options, as shown in the image above.

How It Works

When the user enters their Twitter username and password in the form (shown above), the plugin submits those to the Twitter API to verfiy the credentials. If verified, the user can then post comments using their Twitter account. Their Twitter 'display name' will be shown beside their comments, and their Twitter avatar (profile photo) will be imported and shown beside their comments (if userpics are enabled in your templates).

Note that users' Twitter passwords are not stored in the MT database. An upcoming version of this plugin will enable Twitter's new OAuth support, in which case passwords would never be sent to MT at all. That version will like have an option for commenters to cc. their comments to their Twitter account. Stay tuned.

  • Net::Twitter perl module (included with plugin)
  • JSON::Any perl (included with plugin)

Note: Net::Twitter requires newer versions of the libwww-perl collection of Perl modules. I am not sure what the minimum version required is, but on my server, I had to upgrade in order to get Net::Twitter to work. So if you get strange errors, try installing the latest version in your 'extlib' directory of your MT.
