Elitwee MyTwitter for WordPress allows users to display their recent tweets on their blog and update their status through the Options page.
Configure the options for your Twitter profile using the Elitwee MyTwitter panel in the Settings pane of WordPress.
Enable Elitwee MyTwitter in the WordPress Widgets administration screen. Alternatively, you can include the mytwitter() function in your theme template anywhere you want to display your tweets.
Example CSS code is included in example.css. To incorporate on your site, copy/edit the code to the stylesheet for your current wordpress theme. For most themes, this can be done by going to Presentation -> Theme Editor and then select "Stylesheet" from the theme files list.
