I run Seti@Home mainly because I heard about it years ago and decided to take part in it. I unfortunately was unable to carry over my credit from the previous setup as I never really cared about remembering the password or maintaining that email account.
This project is either a waste of time or will require a major overhal on many beliefs (religious oriented). Personally I would like to believe that this project will cause for a new path in the future.
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.
