Bidding for work at CodeCogs.com is straightforward. By clicking on the “xx OPEN MODULE REQUESTS” text on the bottom left of most screens, or by clicking on the Contribute tab, and then clicking on the “Modules Wanted” option from the menu on the left., you will be taken to a screen where you can view all of the open module requests.

Clicking on the name of each module will bring up the requesters details of the request. If you are able to do the work then click on the 'BID' button to place a development bid. If other bids have already been placed, you can view the complete bidding history by clicking on the number of bids. You can subsequently view your bids (in MyCogs-> Development Bids Made) and cancel your bid at any time prior the requester accepts your bid.
