This is ridiculous, why is this not posted in the systems issues area somewhere.
Just got off the phone with Ebay and we were told that 15% of all of their accounts have been affected with User IDs and Accounts disappearing completely. They said it is an extremely high priority to get this resolved. They have contacted Tech people that are even on vacation to pull in as much help as possible. They said they will address any problems with current auctions that will be ending today.
