Um, considering PC itself doesn't even make enough from donations to cover all the costs of the server and whatnot, I don't see why we'd start a separate donation drive for something unrelated. Not to sound heartless or anything, but I'd rather keep funds for PC. It'd be nice idea if we were self-sustaining but otherwise, I just don't see it working out. We don't even have the means/popularity to do something like some other gaming sites do (ie, speedrun gaming marathons for charity, etc.) Plus, considering how young our member base is, it just wouldn't work out.
Besides, if anyone actually wants to spend their money to donate to a charity, they're probably going to go out of their way to donate to one locally or through the charity's own site. :/ Having two paypal donation buttons would just be confusing.
