Once you log in to WorkerANT, "My Summary" page will be shown. In the menu on the left hand side of the page, under the title "My Work", click on Bidding. This will take you to a list of all the adverts you are currently bidding on.  

NB. If you want to remove your bid before bidding closes you can do so by clicking Remove Bid on the menu along the top of this section under the heading "My bidding". There is also the option to edit your bid, which you can do by clicking Edit bid, located in the same menu.

Once a listing comes to an end, your bid will automatically move into either your "Won" or "Didn't win" folder.
