While installing and using this script, I discovered about a small black dash placed before the button image (and working as a link).
I quickly found out it's due to this (in main.js):
jQuery('#' + theID).append('<a class="cb_pin_link" href="#"> </a>');
needs of course to be removed.
Apart from this, I think the script works perfectly... I'd only wish there was the chance to include the first lines of the blog post in the pin-it description... do you know if that's possible?
Thank you very much,
