ACOR is one of the original social networks, created long before the term became one of the buzzwords of the web 2.0 explosion of services. Since September 1995 ACOR users interested in specific and often rare form of cancers have benefited from the collective intelligence of hundreds of patients and caregivers. 

The heart of ACOR is a large collection of cancer-related Internet mailing lists , which delivered over 1,5 million e-mail messages last week to subscribers across the globe. In addition to supporting the mailing lists, ACOR develops and hosts state-of-the-art Internet-based knowledge systems that allow the public to find and use credible information relevant to their illness.
