Use of the watch list itself may not be a tactic, but it sure makes it easier to monitor the activity on various bids ... if you've only bid on one or two things, it's not as handy a tool as if you've bid on several (or, as I've sometimes done, many) ... dunno about the rest of you, but if I've got half a dozen bids or more open, it's sometimes easy to overlook one or two of them ...
