Thanks to the GWGuardian spam detector we have running here at the
School, the list has been spared up to now of a lot of spam.
Unfortunately, someone has been using some listers addresses to send out
viruses. Please be careful if you receive mail from a name familiar to
the list. The list does not ordinarilly send out attachments, so
please check twice before opening any unsolicited attachments--does not
take much time or effort to send an email back to the person who
purportedly sent you the attachment to check.
