By the way, is there a feature in Gmail such that it would remind me about an e-mail if it is not replied to? For example if I ask a client "should the icon be in cornflower blue?" I'd like to be reminded if they haven't replied to it in X hours.
I don't think there is a way to do this automatically, but I've been using the super stars in GMail for this. I use one of them to mark emails that I'm waiting for a reply on, so I can follow up with people if I don't hear from them for a while.
