problems with Bro mailing list

The Bro mailing list is experiencing some significant problems at the
moment (Hopefully you folks will receive this note!): (1) the archive is
unretrievable, and (2) some posters who are indeed on the mailing list are
having their posts denied as coming from a non-member.

I am aiming to fix both these problems by moving the mailing list to
a new home, hopefully by the end of the week.

Sorry about the hassle ....
