NOTICE TO SUBSCRIBERS
     As an experiment, the Central Bureau decided not to issue
telegrams (telexes, mailgrams) recently, specifically with regard
to the comets and supernovae discovered during the past week.  It
has been felt for some time that the Circulars are getting such
rapid and wide distribution electronically that the telegrams have
become superfluous.  There are now very few countries with active
observatories that cannot receive electronic mail, and any amateur
astronomer who subscribes to a widespread network, such as
Compuserve, can also easily subscribe to the e-mail Circulars.  It
certainly seems not to be the case that the absence of telegrams in
the past week has caused important observations to be missed.  On
the other hand, in comparison with the Circulars, the telegrams
contain extremely little information, and they are also expensive
both for subscribers to receive and for the Central Bureau to send
(and to maintain address lists with the telegraph company).  Comments
from telegram subscribers are solicited.  Unless there are good
reasons for continuing the telegram service, the Central Bureau would
like to phase it out, transferring any remaining credit balances to
the corresponding Circulars accounts.
