I started running Seti@Home a long time ago, but stopped for some reason I cannot recall. After watching "Are We Alone" on the Science Channel, I was reintroduced to it.
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
