If a user wants to use an online file provider to upload files to a review request, they need to be able to create accounts and make changes as necessary. This would be allowed through the My Account page of a user. On this page, users would be able to see a list of all of their file provider accounts and delete any as necessarry. There is also a form for the user to create a new file provider account by select a provider name from the drop-menu and typing in an account name to associate with it.
All of the creations and deletions are done through web api calls, instead of form submissions to the server. As such, the calls would have error or success messages on screen.

Manual testing, and debugging at each part.
