I've found a new community and link building site at pimpmyblog.eu . Although there are a bunch of such sites on the net this site seams to be a bit different. Here are some features

• Build you own minisite, and classify the pages into the oppropriate categories
• Run your own blog on pimpmyblog.eu
• Create your own chat room to chat with your friends
• Open and manage your own special interest group
• Run you own forum with public and private (only members of your group)

But the main important issue is that you'll earn money for all ads displayed on your pages and the pages of your downline. These are additional features of pimpmyblog.eu :

• A section to place classified ads for free
• There are several themes to to select from to get an individual design
• Manage your own picture galerie

Cooming soon:

• A software to build your own family tree
• There are several themes to to select from to get an individual design
• An enhanced Facebook application development environment
