Networks feature - group people by custom fields value

Hi,

i am a former SocialEngine user, this script have a great feature : networks ! a quote from the official website :

Create networks to organize your members based on profile information they have in common.

Networks can be universities, organizations, workplaces, countries, cities, age groups...essentially anything you want. By default, member's network associations are shown on their profile.
The main activity feed can be set to only show items from member's peers in their networks.
Networks can be used to keep groups of members and their content separate from one another.

you can check this post :

The main uses of this feature are :

> auto group people based on fields value (group all people using photoshop for ex)
> show in the stream only the activities of the members of member's network

I think its some thing that can be very usefull for many kinds of communities/social network.

SocialEngine is complete social networking script and standalone software. the main inconvenient of this script is perfomance, its really really slow, you need at least a vps! we use it two years with a website then we stop.
