There is currently no way of telling if an item has bids or not except by clicking on the listing. And even then, it's not obvious. You have to scroll to the bottom of the page to see the bidders list.
Also, the flashing "r" symbol doesn't mean anything to a newbie to the site.
Would it be possible for the price of an item with bids to be displayed in a different colour? (bright £££ GREEN being preferable)
This would make it easier for potential bidders to see auctions that already have bids and encourage them to join in the bidding action. It also makes the site look busier and more "alive".
