Afraid that the last message you received from this list was spam. To
reassure you, I have removed and banned the member concerned, who I
imagine joined purely to send the "millionaire" email and post a link
to that website in our group site links folder. I have also deleted
the message and the link.

To avoid anyone else joining in order to sneak unwanted links or
files onto the site, I have changed the group site settings so only I
can add links and files. With an open membership list we can't avoid
the odd person joining just to send irritating emails. However, one
strike and they are out :)
