First I would make a seti directory.
is what I use. Then download <A HREF="http://ftp://alien.ssl.berkeley.edu/pub/setiathome-3.08.i386-winnt-cmdline.exe"
target="_new">the comand line version of seti</A> and <A HREF="http://www.wakeassoc.com/setidriver/" target="_new">SetiDriver</A>. Put both files in your seti directory, and uncompress the setidriver archive you downloaded. Start up seti driver and set your desired cache size (I use 10), select auto transmit (if you're on broadband), and hide processing. The seti command line window will pop up, and then select "use existing account" and I'll PM you an email address to enter.
Then just make a shortcut to seti driver and put it in your startup folder.
It's safe, it runs completely in the background and doesn't slow down your computer at all. Right now on my system setidriver is using 1.4 MB of ram and seti itself is using 14 MB of ram.
