Getting rid of rounded module borders

I need to make them squared off and I can't find that attribute in any of the CSS so it's got to be a tag I don't know about.. any help would be appreciated

Nevermind, for those that need to add this css to jomsocial or some other integration the CSS is in css3.css

-webkit-border-radius: 3px; -moz-border-radius: 3px; border-radius: 3px;
