the setupcode for mysite is:
<script type="text/javascript">
//<![CDATA[
(function() {
var shr = document.createElement('script');
shr.setAttribute('data-cfasync', 'false');
shr.src = '//dsms0rr1bbhn4.cloudfront.net/assets/pub/shareaholic.js';
shr.type = 'text/javascript'; shr.async = 'true';
shr.onload = shr.onreadystatechange = function() {
var rs = this.readyState;
if (rs && rs != 'complete' && rs != 'loaded') return;
var site_id = '256ae0dda0e8433a0b2bd7b9b28';
try { Shareaholic.init(site_id); } catch (e) {}
};
var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(shr, s);
})();
//]]>
</script>
As far as a url to use. Since the buttons can be added anywhere on the site, using your example:
ubbcentral.com
At least that is the way I set it up.
You can add as many sites as you wish,as well as different buttons and locations.
