[Nauty] mailing list information

[Brendan McKay]

Dear Nauty-list members,  In recent days the number of spam messages to
nauty-list has grown enormously and now there are more than 30 per day.
You should not be receiving them because of our only-members-can-post
policy, but please inform me if you are.  The only effect you need to
be aware of is that I have started to discard all non-member postings
without looking at them.  If you post from an address different from the
address you subscribed under, your message will just vanish instead of
being helped along by me as in the past. 

It is OK to subscribe under more than one address if you wish.  If you
do that you can disable delivery of messages on all but one of them.

Brendan.
