I tried for Europe - the genuine one, but it was so long winding and full of nonsense I gave it up. I'm quite happy with my dot.tk ones for now. Now and then over the years I've tried .co.uk and I thought one had to be a citizen of the UK to qualify for a .co.uk Website. Is it different for the US, i.e. any one from the world may have a .us Website regardless of whether they are US citizens or not?
sounds but read the 'fine print'. There are "catches" that may not be in your best interest - i.e. ownership
It says US and Canada only but it's not for free. But I always suspect when they give away top-level domains just like that. It could have a hefty renewal fee or something else. I guess with this one you don't actually own the domain. Could be a major loss if you build a good volume of traffic and they decide to place ads and all.
