The easiest way to do it is to go into rrssb.php, find the functions that return the link, and add class="popup" to the <a> tag. If you want them to just open in a new tab, add target="_blank" instead.
I made them open in a popup. Easy fix. I also show the number of shares in the button now.
If anyone needs help or wants me to show them how, let me know.
