Folding@Home

[Simius]

Maybe this is a dumb question, but how do I see how long it will take to complete a WU?

Do use the Graphic Client? If so, then double-click on the red Folding-Icon in the task bar. This will open a window with all kinds of stats, including the estimated time to finish the current Work Unit.
If you're using the Console Client, you can't see it directly (though you open the file named FAHlog where you can see how many of the total number of steps have been completed.

Why aren't my work units counting? I've contributed 3 so far, but I don't see my name on the list. My internet connection is always established, and the program is always running fine.

Are you sure you've inserted the proper Team Number (82447) in the configuration?
