Hey Trevor,

I am really sorry for the delay of this reply as it is a weekend for us here. You can actually edit the file in /components/com_easyblog/themes/wireframe/socialbuttons/pinterest.php

If you are going to modify the file, it's recommended that you follow the template overriding guide here, http://stackideas.com/docs/easyblog/administrators/customizations/template-overriding
