I was playing a game online (this one, if that's important: http://devpro.org/) and ended up angering my opponent when I made an unconventional play that won me the game. Afterwards, he insulted me, and I responded with smug satisfaction. In response, he said he wasn't mad, because he was "taking my IP." He mentioned something about "packages" before ceasing to respond. Is this something I should be worried about? Is this something he would be able to do simply using the game, and if so, what are the implications? I don't know much about computers - any and all help would be appreciated!

I'm doing a science fair project in which I test water for various substances... Are there any cost-effective ways in which I can test for salt in water? I'm also using food coloring as an industrial chemical substitute... Are there cheap ways in which I can measure for this (by the way... I need measurements, not just to know of presence).

I know this sounds stereotypical, but I don't get why they are so against atheists. This is truly not a Christian nation, and I don't care who says it is. On TV, all I see is a bunch of theists debating about what reasons atheists have not to believe. What we need is an atheist to stand up, and explain our beliefs and why we believe that. Why is it so hard?

I was considering buying and wondering if the wiimote was included.
