I am not sure how much I want to bother clients by rating my responses. It's a faff, and provides no real reward for them. There's too much junk at the bottom of emails anyway. I'd also not want to apply it to all emails - and there's a fuzzy line (where I work) between clients, providers, and random other contacts.<p>Having said that, I do love it when someone responds with a "Thank You". Or, in the case of one memorable client, poems praising how quickly the problem has been solved. <3 those.
