A Private Social Network For You And 11 Friends [1]

Social networks such as Facebook are great if you want to live your life in public. But what if you want to use a similar type of system to collaborate online with friends or colleagues in a more private way? Perhaps you're working from separate locations on a business proposal, a party plan, a family trip, a special celebration, and so on, and you want to be able to share to-do lists, photos, calendars, documents, messages, and everything else to help you keep track of everything.

Bitrix24 is such a service, and if your group of like-minded people numbers no more than 12 individuals, then it's completely free to sign up and use. All you need is a web browser. Just go to https://www.bitrix24.com/ [3] to get started. Your account even comes with 5 GB of online storage for all that project-related information, which should be plenty.
