I am thinking about installing a file sharing software systems. For example, Imesh, KaZaa Lite, or eDonkey, to name a few. (These are the ones that I know of, I am sure there are more?)
1. Which is the best choice out of all of them?
2. What are some of the things that I should be concerned about?
3. Are they hard to use?
My main concern is causing harm to my computer?
