I just tried this in version 6.19.2.8555 (308555) Public (CE Build ce-62.3.7750), and can't see a way to change the color. I know it is (or was) possible, because some of my notebooks have a different color font. Any further advice?
There seems to be some confusion here. EDH mentioned something in his signature. I and others do not see his signature. I was asking if there was a setting to see his signature. I am not interested in adding one of my own. As far as I know, that question has not been answered.
