just let your nephews play Quake and UnReal Tournament on your laptop all turkey dayI also hate cheaters. Still, I don't think this can be considered as cheating. Depends on how often other persons are using your computer. If it's every now and then: forget it. If it's continously and a high amount of your "moves" has been done by somebody else: forget it.*cough*
With all those Type-, Scroll-, Move-, Klick-, Whatever- projects it is hard to define what cheating is. If my code is not working and I smash my keyboard, do I cheat? When I click F5 10 minutes long once a second since my favourite homepage shows "too many connections"? When I start painting like mad in paintbrush abain: cheating?
Ok, if somebody else is using your computer it's even harder to tell. On the other hand, while he's using your's you can't use it. So I guess it's ok for me.
