Before you say/assume that this plugin is not working or you encounter an error, check these out:

• PHP 5 is recommended. Though, this plugin may run on PHP 4
• Your web server must support/provide PHP CURL extension and SimpleXML
• Make sure you only type in your twitter username in the Username field on the configuration page. Not your twitter email and without the @ tag. Just the username.
• In case you encounter a messed up or strange layout, it means that your WordPress theme is not compatible. You may post your issue on http://forum.xhanch.com/index.php/board,9.0.html
