Having difficulty with the upload widget?
NOTE: If the "Add" button appears to do nothing, and/or you are unable to drag a file and have the "target box" highlight, then your browser is blocking the widget. Please make sure your browser is not blocking third-party party cookies (the widget is from Exavault - a third-party file upload service). You can restore the setting as soon as your files have been uploaded.
