I wanted to give you 23 dollars but my concience said that you can just get a free webhosting thing with a free domain like co.nr or you could just stop working on cubecrape for a bit so that you can pay the payment for the website.
While that's true, it would be a HUGE pain in the butt.
First of all, free webhosts don't allow PHP or MySQL. My site uses 4 tables- It is almost entirely powered by SQL.
Second, .co.nr or .tk are much less professional than .net or .com (which is taken)
Third, there would be no way to automatically benefit Donators.
Finally, free sites have annoying banners and bandwidth caps, and often don't provide direct links.
Seriously, give me one successful project that is hosted on a free site with a free domain and I'll eat my hat.
