2. Twitter Feed

Admin Control Panel

The control functions such as connecting to a Twitter account and storing information on the tweets/blogs, can be accessed through the “Twitter Control” GUI in the WordPress admin panel.

Any changes in the currently active Twitter account tweets can be immediately updated by clicking on the “Update Blogs” button.

Order, Prioritisation and PM Filtering

The application will display the latest tweet from all of the active accounts and then displays those latest tweets in date order. So the newest tweet across all of the accounts will always be shown first. It is also possible to switch between allowing/disallowing PM (Private Message) tweets to be included in the display.

3. WP to Twitter

The WP-to-Twitter plugin posts a Twitter status update from your WordPress blog using either the Cli.gs or Bit.ly URL shortening services to provide a link back to your post from Twitter.

For both services you can provide your information to maintain a list of your shortened URLs with your URL shortening service for statistics and your own records.

The plugin can send a default message for updating or editing posts or pages, but also allows you to write a custom Tweet for your post which says whatever you want. By default, the shortened URL from Cli.gs is appended to the end of your message, so you should keep that in mind when writing your custom Tweet.
