Always enjoy doing my part to help science prove there's extra-terrestrial life out there. And for my part, as small as it may be, I was sent a lovely little certificate of appreciation. Awwwwwwwwwwww. If you're so inclined to help, and it's cool, if for no other reason than watching the graphs when extremely bored, have a look at their site. SETI@home Both PC and MAC users can do it, and there's lots of neat add-ons which I'm just now getting into. :)
