[newbie] seti at home

[pete moss]

anyone using seti@home?  i have the unix version running as a cron job. 
what does the -nice option refer to.  the default is 1, but it
recommends setting it to 19 if run by cron.  what is the difference?
i have sent this same quesion to seti at home, but i dont think they are
ever going to get back to me.

:P
