How to put in a title under the twitter logo?

Hi,
I am using the code form
<form class=”tb-widget-configuration” id=”tweetblender1″ style=”width: 300px; float: left;” action=”#”>
<div>dfgdf<input type=”hidden” name=”sources” value=”####” />
<input type=”hidden” name=”refreshRate” value=”60″ />

<input type=”hidden” name=”tweetsNum” value=”4″ />
<input type=”hidden” name=”viewMoreUrl” value=”https://twitter.com/TheBench_ie&#8221; />
<input type=”hidden” name=”viewMoreText” value=”Follow Us!” /></div>
</form>

I want to put “Brought to you by my username” under the main logo.
Which files can I edit to achieve this?
