Mike,
Thanks again. We all have our own areas of interest and I think that naturally shows itself in the areas we research. What this points to is how varied the disease is, there is a whole continuum, not just two, (or 3 or 4) types. As you know, its difficult enough communicating information about just two types, and getting people to act on that information. I will be researching this more myself in the next couple of weeks and will communicate with you on that.
