Did you know.....? If you want to grab another Copenworlder's attention, you can "mention" them in a message. Simply use the @ symbol followed by their user name (with no space in between), e.g. @copenworld would shout out to me. As you start to type their user name, a pop-up box will list any matching names to make it easier to find the right person, and you can choose from the list. You'll get an alert when you're mentioned by anyone, unless you switch this option off in your user preferences.
