If you’re interested in setting up a group/community/social network, perhaps you might like to check out ‘The Fridge.’ The Fridge is a place where you can set up a free group/community/social network. There are plenty of places these days for setting up a group and/or a social network. You could of course try Google Groups, Grou.ps and/or Yahoo Groups. If you are happy to pay there are other possibilities including Ning. The Fridge is not a site I had even heard of until a few days ago, but it could be worth a look or worth experimenting with for a while.
A member of a Fridge group gets a personal profile, which has a wall similar to Facebook. You can also post a photo for your profile. It really is a very simple social network providing a very basic service. It really seems to be a way of having very basic communication with other members of the group. You can post a picture with a post. So basically it provides a secure and private place for communicating. I guess email really accomplishes the same thing to some degree.
