Affiliate an existing OSF project with WU OSF
Once a user has affiliated their account with Washington University in St Louis, any new or existing project can have Washington University in St Louis affiliation applied (via the project "Settings") and the institutional logo will appear on the project. Any projects with affiliation that are also PUBLIC, will appear on the OSF landing page.
