Use case 1: 

Mr X is a student at UoR in his final year. He is job hunting, but has found it difficult, because he hasn't received any grades yet, nor has he finished his exams yet. Luckily he his been able to gather all of his coursework and validated exam results from previous years using the MeAggregator, which has enabled him to create a "view" of his work on a website, which he shows different companies. The MeAggregator has also allowed him to create a pdf file of the material, which he has showed of at various graduate fairs.

Use case 2: 

Miss Y is a keen programmer that would like to be involved in a open source games project. Unfortunately she doesn't know anybody who shares the same passion (strange  she is a CS student, hmnn!) Through the tags and trust network of the MeAggregator she has been able to find two other students at Kings who wants to create a network based game for girls. Because the trust levels of the students are high she has decided to contact them to see if she can be part of the project.
