             The following example downloads the EQSL user list and checks if DH1TW is a user:
  
             >>> from pyhamtools.qsl import get_eqsl_users
             >>> mylist = get_eqsl_users()
             >>> try:

             >>> except ValueError as e:
             >>>    print e
             'DH1TW' is not in list
