Social Groups are a new feature of the site. Its a way for people of similar interests to discuss thingd particular to them. For example, I created Social Groups for site members who reside in the Dallas area and Texas. Then we can keep each other up to date on things happening in our area.
One might create a group for IBM support specialists here they can exchange information of value to them but not necessarily for everyone else.
Or perhaps someone wants to create a social group for German speaking members. Within that social group, they can feel free to post in their native tongue.
The uses are limited only by your imagination.
Feel free to view the social groups or start new ones. Just one more feature to make this the best pSeries/System p/POWER Systems support site on the web.
