As mentioned in my post ( http://www.vbseo.com/f2/counting-social-bookmark-usage-37818/#post243234 ), it would require a minimum coding to achieve as GA now supports event tracking and it would prove very useful to gain an insight on how your members use the social bookmarking functionality brought by VBseo. Ideally, we could event differentiate the thread bookmarking from the post one.

Any questions, please feel free to PM me on the forum (username: coume)
Thanks
