Interesting... Why can't they let us choose which project gets our extra processing cycles? It seems only fair.
You can! They are switching to BOINC. There is a really neat project that is looking for gravity waves. http://einstein.phys.uwm.edu/
One useful fact: After you establish your account and download and install BOINC Manager, go to the File Menu.Select Computer...
Enter "localhost" the Password should fill in.
If it doesn't, look in the file c:\Program Files\BOINC\gui_rpc_auth.cfg with notepad. Copy the string you find there, it is your password. Paste it down in the password box.
It took me about two hours to find this out.
Unless something's changed, you can pick your project. When I switched from seti@home to BOINC, I was given that option.
