Good idea.
Nah...I wouldn’t do that if I were you. It would look like Tinky Winky. You remember from the past what happens when you start changing the basic fonts and colors of the posts...LOL I know they are not exactly like your dad created them, but they are close. Somehow he was guided in the beginning to pick out a pleasing font and color. That is a part of him that should always remain in the software IMHO.
