I cannot tell you how annoying it is that I messaged some of the merchants here over a month ago and have not gotten a response, let alone a notification that they got my message. Add to the feature request list, if you will, email notification of instant messages -- or contrarily, merchants who give a damn about someone who wants to buy something from them, but only if it meets a certain requirement. Of course, I know you can't do that last. But still.
