The Open Science Framework (osf.io) is a system for managing project data, documents, and research materials. You can use OSF to track, collaborate, and share your research.
OSF is run by the Center for Open Science, a non-profit organization that seeks to improve the openness, integrity, and reproducibility of research. It is free and Open Source.
Note: If you already have an OSF account, make sure that you have your gmu.edu email as the primary email address. Otherwise, it will create another account for you.
