Thanks for your comments Jan.
Maybe I should be using a message to group, rather than announcement, as you say.
I understand the difference between roles and group.
However, what I desperately need to do is message a group, [b]but stop people replying and CC’ing the entire group![/b]
People think they are only replying to me (and not the whole group) and that causes a whole lot of privacy/data protection issues.
