BLUEPRINT: The Progressive Network at American University. The American University YP4 Fellows built upon work begun by the class of 2005 YP4 Fellows. They continued to develop and initiated a university wide progressive network, appropriately called The Progressive Network. The mission of the network was to increase the unity, size, and effectiveness of the AU progressive community. The Fellows wanted to encourage more students to be progressive and to motivate and empower those students already involved in progressive organizations.
