<script type="text/javascipt"> tumblrTweets("span.label"); </script>
span.label is the CSS Selector for the elements you wish to scan. You can link to these files from my web server if you like3 (check the source of any of these pages), but if you have your own hosting please use that instead, I only have limited bandwidth!
