    <p>We Eatt is offline today, because the US Senate is considering legislation that would certainly kill us forever. The legislation is called the PROTECT IP Act (PIPA) and like SOPA, is the worst.thing.ever. Well, the worst legislation concering the internet ever, for sure.</p>
    <p>Basically, it would shut this site down -- we would be legally responsible for policing the content that users upload. For We Eatt, that means <i>SOMEHOW</i> guaranteeing that the recipes users upload do not infringe anyone else's recipes anywhere in the world. We Eatt would shut down.</p>
		<p>We don't want that. If you don't want it either, visit <a href="http://americancensorship.org">AmericanCensorship.org</a> for instructions on contacting your Senator. The <a href="http://blacklists.eff.org">Electronic Frontier Foundation</a> has more information on this and other issues central to your freedom online.</p>
    <p>Thanks,
