* Uploading files is now available with an optional Flash Uploader which shows a

nice widget with information on the upload progress. It makes it possible to select

multiple files at once. Enable the Flash Uploader by checking the appropriate checkbox

in the User Setup, reload the Backend and make sure that your browser has the

latest version of Flash (Flash v9+) installed.
