The Jomsocial - K2 Integration is a commercial extension for the K2 component.
The Jomsocial-K2 Integration plugin synchronizes K2 and Jomsocial users, replaces all user links/avatars/info in K2 pages with the ones from Jomsocial and inserts activities into the Jomsocial activity stream when a K2 item is created or updated.
NO core hacks
There are absolutely NO core hacks in this extension.
This means that you don't have to go through painful file replacements when you update the components.
1. Users links/avatars/info synchronization
This includes the K2 Category page (listings), the K2 Item page, the K2 Author page and the K2 Comments block.
2. Jomsocial activity stream integration
When a new K2 item is created or updated, the activity is inserted into the Jomsocial activity stream.
3. User level integration
This means that when a new user is registered through the Jomsocial registration, this user is automatically assigned as a registered K2 user.
