You can delete Users in Security by going to Tools, Security. This will bring up the Security Administration window.

1. Highlight the name of the user you want to delete

2. Click the delete button

3. You will be asked if you want to remove the user; select "Yes".

A "Reassign Tasks" window will appear, prompting you to reassign the deleted user's tasks to another user. Select the user you want to reassign the tasks to from the drop-down menu. After this, the Security Changes window will remind you that you need to log out before these changes will take place.

After deleting a User, you can still view their audit log. To do so, log in as the administrator.  You will check the "Include Inactive Users" box.
