Does Joomla Social allow for :

i) Private groups and document sharing ?
ii) Can it be integrated into my joomla website ?

Hi Dwayne,

Jomsocial lets create private groups and there is also a section called discussions that lets you share files in a group.
Jomsocial installs into the current version of joomla.

You can see the features of Jomsocial here demo.jomsocial.com if you have any further questions please reply and i can assist you further
