Requirements for using BSCW are minimal:

• You must have a personal email address to register as a user of a BSCW server.
• To access shared workspaces and to download documents to your local computer you need a web browser that supports forms and basic authentication. Most browsers (e.g. Netscape Navigator and MS Internet Explorer ...) do that. We recommend using latest versions of e.g. Netscape's Navigator or MS Internet Explorer.
• The easiest way to upload documents to a BSCW workspace is to use the built-in file upload function of Navigator or Internet Explorer. For other browsers you may need to install a small BSCW Helper program (see section 4.14). You may download it free of charge from the public BSCW server at FIT (http://bscw.gmd.de).
  BSCW Helper programs are currently available for several UNIX variants (including Solaris, SunOS, HP-UX, AIX), for Macintosh (MacOS) and Windows.
