How does one get similar functionality to this community? I installed K2 and Joomla with the JASocial theme from Joomlart and I would like to be able to have the same type of functionality as this community.Are there special plugins I need? There seems to be some customization done to have a user menu with the inbox, friends, settings and quick add dropdown as well as the blog front end editor looks different.What do I need to duplicated this?

This Community was build in NinG Network - nothing is Joomla except the content :)

If you would like to built a Social Com with Joomla JomSocial would be an example.
