I went to twitter.com/goodies/widgets and generated code for a twitter widget which I then pasted into the wordpress site I'm working on. The site is http://msmdesignz-testing.info/wp. The red twitter widget can be viewed on the right hand side towards the bottom, under "Digistar Tweets."
Since the person's name is the same as their twitter handle, I wanted to get rid of the top name and just keep the larger link underneath. I'm able to use firefox's 'inspect element' feature to see that the top name is enclosed in an <h3> tag, but I don't know where in the wordpress files that html code is stored.
