Differences in Social Groups in VB3 vs VB4?

[MikeJeffs]

Hi,

I have a license that I was intending to launch a site with. However, after configuring the site, I felt the social groups features weren't quite mature enough, and since the groups were to be an integral part of the site I decided to hold out.

I'm wondering what, if any additions have been made to the social groups feature?

Thanks
