I have completed all the Challenges and earned 5 badges on January 30th, 2016. But I didnt get an email. 
May be I was wrong in filling the form somewhere. I waited the 2 hours to recieve the email notice, but have not seen it.

How should I get the Sweat-Shirt ?

Please help me !!

Thanks in Advance

Project custom object records should only be seen by the owner of the record and users above the owner on the role hierarchy. However, for some Project records, the Training Coordinator must also have Read Only visibility to the Project record.

Create a custom picklist field on the Project object called “Priority” with the following values: High, Medium, and Low. Then create a criteria-based Sharing Rule for Project records where the Priority = High to share those records with the Training Coordinator role.
