Everyone knows how important feedback is on eBay, but it can be difficult to find time to keep track of who needs feedback and to keep filling out the same forms over and over. InstantFeedback makes it easy. It sits in your system tray and quietly checks your feedback for you at any interval you specify watching for fellow eBayers to post for you. When they do, Merlin will automatically post positive feedback for them from either a list of premade comments, your own custom comments, or one at random. If you should happen to get negative or neutral feedback, you will immediately be notified so you can rectify the situation quickly. You also have the option of mass-posting feedback for everyone who has left feedback for you starting back a specified number of days, whether they've left it for you or not. You have the option to not post for auctions you've bought, only for auctions they've sold, so you can wait for the item to be received and found satisfactory.
