Why do you ask for advice and then turn around and say, "No it's not!" Quit whining. It's funny, Regs out of Boston uses straight letters too. I don't really care one way or the other, but your excuse is lame, to say there aren't enough 3-7 letter words. Gimme a break. Good writers tend to be smart and creative. You are a nagging biter.

why not write Urge instead. It sounds more your style, and you get to keep the R, the E, and the G.
