How to Add a Retweet Button to the Twitter Web Interface
‘Retweeting’ is the process of sharing a tweet that you like with your Twitter followers. Basically this involves copying and pasting the whole tweet in your tweet box and adding a ‘RT’ in front of the tweet or a ‘via’ at the back of the tweet.
Most Twitter clients have the retweet function built in but if you’re using the web interface, you can also include a retweet button using a greasemonkey script called Retweet This. You’ll need to use a browser like Firefox or Flock though.
