Finished Interviewing Material

I've decided to put 6 people on the poster instead of 9, because I think it'll fetch far more satisfying results. This is because instead of 3 of each (student/teaching staff/ordinary staff), we now have 1 lecturer, 2 non teaching staff and 3 students. Let me know who you think is who? (I'll assemble their real roles at the bottom)

It would be great if we could start interviewing this week or as soon as so we can get a good start on the final project.
