I am a college instructor... I know busy. However, when I have an auction I don't go 3 days without answering my comments. I have also had very bad experiences bidding on auctions where the seller doesn't comment within a 24 hour period, so I get very suspicious when I see it happening. Sorry to insult you, but you might want to check in at least once every evening when you have an auction :) When you answer within 24 hours, you get a lot more bidders. You will see :)
