I\'ve used this example to retrieve my twitter feeds however it has an error
The remote server returned an error: (400) Bad Request.
Have you tried manually going to "http://twitter.com/statuses/user_timeline/" + User + ".rss" in your browser, and seeing if you get a 400 error there? I'm guessing a typo in your user name when you call Twitter.Parse(UserName);
Twitter.Parse(UserName)
