Tterb, if you want to keep a scrap copy for personal sakes, fine, then keep it as it is now.
You're wrong, it is not one word spelled wrong. The same word spelled wrong twice is equal to two words spelled wrong. First, as a reader, I want to see it correct in the title. Then, I want to see it in the body of the comic.
You know, if I'm passing around a printed color copy of your comic, I would be proud with the words as they were meant to be. It's a piece of art to some.
Take pride in your work. It doesn't take much retyping for a redo if you want to go beyond a personal copy.
