If you are interested in MS and CCSVI breaking news, then I would strongly advise you to register on the mailing lists for these sites:
ThisIsMS.com site. Being a "friend" or group member of the CCSVI in Multiple Sclerosis Facebook site will keep you in touch with a lot of the research and developments that are happening in the subject area. As well, the Direct MS site, which used to focus on MS and diet, has now set its sights on bringing CCSVI research to Canada.
If you have any other sites that you feel I should include in this list, please let me know.
