this is just a "placeholder page" if you search the ftp access, you probably want to try: ftp access (needs useraccount)
or ftp demo access(upload only) guest ftp upload only access
you may also use your favorite ftp-utility with the following access data: servername: sirup.tuxinator.org port: 21 user:(guest.upload for demo upload) else the username that has been provided to you by sirup.
