Interesting. I tried to get into the Arise pre-sale, and got an email saying "send 0 ETH to this address" and reported it to their support team. That wasn't the only bug I noticed. The support guy was nice, he said he'd honor the "0 ETH" and sent me an email indicating that I'd have some Arise when it went live.
Didn't even consider purchasing any more, due to the typos -- my thinking being, if they're that sloppy with their textual output, they're likely also hiring sloppy developers.
