Clicking the Delete User button produces a wizard style interface for deleting a user account from a openCDMS study. In the initial page of the wizard, you must provide a first name and last name for the user you wish to delete. If no user account exists for the first name and last name which you have entered you will not be permitted to proceed. It is possible to enter either the first name and last name of the user or to enter the user id. If a user account is found, you may choose which studies you wish to delete the user. If multiple matches are found to the names you entered, you will be presented with a list from which you must choose the user you mean. Studies may be chosen by selecting the study names from the list and using the right and left arrow buttons (as in add user and modify user).
