You can select to share the url of the current page or the url of the site (eg. mysite.com/thispage or only mysite.com)
Very light and simple to use.
This module is really unobstrusive and very elegant.
It is, when having knowledge how to modify images, very easy to adjust the grey buttons according to the design of the website.
Great little module and highly recommendable for all webdevelopers who dislike the "loud" big buttons.
