I've been interested in the Search for Extra-Terrestrial Intelligence since I read my first science-fiction book as a teenager.
Later I read Contact by Carl Sagan.
That's when I (and my beagles) became supporters of the SETI@home distributed computing project.
I've been an active supporter since 2 Jun 1999.
On 19 May 2012, my profile was featured as the SETI@home user of the day.
