And get rid of this hiding bidders identities on auctions going over £100. Very hard to find shill bidders on auctions otherwise, but unlikely to happen as 'hidden' shill bidders simply make more money for Ebay thanks to the higher final value fees...
and i think all UK sellers should have to accept more than one form of payment. There are some things i've needed and the seller only accepts paypal which i refuse to use now after they screwed my account cause of someone claiming they hadn't received an item i sent (regardless of me sending them the proof of postage)
