Mate I've had to ditch SETI altogether. I think I had only 12 units after having the screensaver for more than a year. My pattern of usage is such that I don't have much screensaver activity and I don't tend to leave the computer on unattended much because of other information on it that is quite sensitive. If I upgrade my computer or finish my project early, then I will check it all out again.
The hassles I have in trying to transfer SETI@home to BOINC (never were resolved) are not worth the effort to resolve so I have wiped the lot.
In fact lately I have come to the realisation that I have been expending quite a lot of time and effort in various things, and the 'cost to benefit' ratio is not in my favour or anybody else's. One of the things I am going to review is how I spend my time on line, both here and on other sites.
