What changes are being made to the eBay Feedback system?

There are five key elements to the new Feedback system being introduced in the first half of 2008:
Beginning in February, buyers and sellers will be able to earn up to one Feedback per week from the same trading partner. Today, members may only affect each other's Feedback scores one time, regardless of the number of transactions between the parties. This change will both encourage repeat transactions and reward good service.
Sellers will no longer be able to leave negative or neutral Feedback for buyers. This change will occur in May, 2008.
Removal of negative and neutral Feedback left by members who are suspended or who fail to respond to the Unpaid Item Process (UPI).
Positive Feedback percentage will be based on the past 12 months of Feedback, rather than lifetime, since it is most indicative of the seller's recent performance.
Restrictions on when Feedback can be left:
Buyers must wait three days before leaving negative or neutral Feedback for sellers with an established track record
Instead of 90 days, members will be able to leave Feedback for 60 days
