I've run SETI@Home off and on since 2001. I keep forgetting my previous information and end up making new accounts. I think this is an awesome project. Since our government barely spends any of the annual budget on space exploration I volunteer my computers to help decipher the information that SETI does get.
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.
