Send an Oceangram
People complain all the time about how they get too many emails - "I never get the chance to work with all these bloody emails people keep sending me". And it's true that the constant mix of work demands, domestic nags and general NSFW can curb your ability to work, but what's the alternative? Maybe people will STFU if you start sending them stuff via Oceangram. You just type your message, put it in a virtual bottle and cast it out into the vast ocean of the internet. So if you've got an urgent message you need to send that absolutely has to get there immediately, remember that you might have more chance of someone seeing it if you just chuck it in the sea.
