Oh,well, (sigh), you can't please everyone. I must say again it looks easy to navigate. Just to compare, I checked in at OBT, which lists everything under the sun, and found I was scrolling forever to get down to my Myasthenia Gravis forum.
Besides which, I checked spinal disorder in the dictionary. Spinal is defined as: of, relating to, or situated near the backbone; of, relating to, or affecting the spinal cord; While disorder is defined as an abnormal physical or mental condition. So a spinal disorder would be an abnormal physical condition of the backbone or the spine. To me that would have to include spinal cord injuries. Therefore a very logical place to put sci.
