For a while I had assumed that the pps sieve stats were not showing on my account page because they are secret as long as it is still in development, but I just found them listed at boincstats.net. I am glad I did because now I'm sure its the best use for my pc. I'm just wondering why there is no pps sieve info on my account page or in server status, but it IS listed on the main page for available WUs? I really like the high factor density, though. Makes me feel useful for once.
