I had a lot of trouble getting started with folding. I didn't know how much of the time I wanted it to run. I didn't know if it was safe for my CPU to run it 24/7. I didn't understand that it really would have no impact on the speed of my day to day tasks. I installed it - multiple times - and removed it. I'm now happily running it on an ongoing basis. So why did I start this thread? 1. To hear why people don't fold, and to answer any questions. 2. In hopes that potential folders can get the answers they/you need. 3. To get the bottom 1/3 of our Macrumors folding team active.
