Trying this out:
There is an option (not the plugin but the widget builder) on the dashboard that will give you some javascript to paste into the head of your page/blog, and then some separate code that you can paste on the page.
And you have to have a Tock account to make it active because it sends people to a tock.com/yourwebsite page. But you probably already knew that.
Kind of a shame you had to wait 6 days to hear from someone (me). As such a new widget, they probably should be on it a little more.
