I think also that a reason people do not respond is that they do not have something valuable to say. There are many posts here that I simply do not know enough about to respond. I would hate to post some arbitrary response to a question and have someone rely on it as truth only to find it causes more problems for them.
I do not have bad symptoms, am about to start Betaseron injections, and am hoping for the best. I think this message board is a good place to learn about the disease from real people, with real experiences.
