I haven't bid on ebay for a while but I used to always get notices sent to the email address associated with my account. When I started reusing, I haven't received any notices. I checked the account preferences and am listed to receive instant notice when I bid, am outbid, win an auction, etc.
Is there something else I should be looking at? I figure this should be pretty basic but I don't see anything in the user preference section that would account for this.
