To Instructors

If you are already familiar with Imaras registration procedures and set up, you may go directly to the Group Information Form. This allows for a timely setup, the same starting date, and pairing with groups from other countries. We organize negotiations every 5-8 weeks. If you are using Imaras for the first time, we recommend reviewing the Instructor's Synopsis. It is a comprehensive review of registration procedures, information about cases and other useful information.

To Web Surfers

To try Imaras you need to fill in a short auction request form.

Bidding via imaras

Imaras^© (InterNeg multi-attribute reverse auction system) is an online auction system powered by Invite^©. It has been developed for teaching and research purposes. We collect and analyse information generated during auctions. We also ask users to fill in two questionnaires. Under no circumstances, however, do we provide or allow access to individual records nor do we disclose any information about any users (e.g., their names or email addresses).

Our users find the system easy and fun to use. They have enjoyed discussions on the Web with unknown opponents. They were able to use different strategies, learn more about auctions and auction support, and work on their communication and auction skills.

Please use Mozilla Firefox 3.5 (or above) or Google Chrome with monitor resolution 1280*1024 (or above).
