Once the contracts of a WorkGroup have been finalised, you may go to "Contracts" Stage, click on "View Contract ..." link and you will see the "Digitally Signed Contract ..." field. A file of type *.rdsc is ready for you to download and we suggest you to do so and keep this file. This file contains all the information of your Contract encrypted and digitally signed by the platform. The Digitally Signed Contract is a means to amplify the reliability of collaboration between members. You may check the validity of a contract using the tool we provide you here.
