We were told about this by a colleague at a training seminar this morning. It's an email sent by their council's IT section.
From March 01 2010 do not send emails to colleagues for immediate messages. Telephone them or arrange to have a meeting. This council promotes conversation.
We every one of us insisted that they forward us a copy of the offending email, simultaneously giving us all a laugh and compromising a ripe bit of corporate idiocy.
