You sit in your garden with some aluminium foil on your head and a carrot up posterior , this is the sign that tells them you are willing for transportation to the mothership.

Thanks, you made me blast my screen with coka cola.
Seriously, what would you say to an ET,
if they spoke your language.
Fact is, we have occasionally sent deliberate messages to the stars. For example, there was the plaque on the Pioneer 10 and 11 spacecraft, with an engraving featuring a friendly couple in natures garb and a map of our location in the Galaxy. The Pioneers interplanetary successors, the Voyagers, carried a crude videodisk, with music, voices, and a small selection of inoffensive photos that could be played with a 16-2/3 rpm turntable and a mechanical needle.
Thirty years ago, a radio message was broadcast by the Arecibo radio telescope to a star cluster in the constellation of Hercules. It was a spartan graphic, amounting to a mere 210 bytes of data.
All our messages have been short and simple. This has led us, I think, to imagine that future cosmic broadcasts would also have to be compact and easily intelligible to beings who (unlike those on TV) will not have mastered English. Messages based on imagery or the regularities of music and mathematics have all been proposed.
The difference between Samuel Morses first, terse telegraph message and the bit stream spewed by a modern telecommunications satellite is enormous. Keep that in mind when you think of contacting other societies with something akin to the Pioneer plaque. Sure, that gold-plated greeting card was a great start, but if we are really thinking about interstellar messages, we should think big.
