This widget allows your site members, site visitors and yourself to ask other friends to visit your page. This is a good way to boost your site view stats.
Once you have dragged the widget to where you want it to be on your site, an edit window will appear.
In this window you will be able to choose which type of 'Invite contacts' button you wish to put on your site page. All of them do the same thing.
When you click on it on your homepage, a window will appear allowing you to choose the recipients you wish to send the invitation to. There is also a social tab where you can choose which social networking site and who to send the link of your site to.
