Shoutbox

I want to send the same message to everyone or selected units without having to go around find them and click them 1 by 1.
Make a script which brings up a box such as the 'Hopper Script' but simply you can select the contacts to send to or click send to all contacts, and even an option to send to offline contacts also so it is there when they log on.
This could help on such situations such as creating a new email account, Log back on old to tell everyone without putting it in your name, using hopper or going around telling everybody. E.g.
________________________________

Seems simple to me..
