Canada and the US have the same country code so you should be able to register using US for now. However, I will have Canada added as a text option shortly. Welcome aboard, mate. Look forward to seeing your contributions to the community!
I'm from Brazil and just to sign up. You mean I get to the NHS, I answer questions in the app or I'll make some kind of bonus?
Yes. There are two bounties as of now. You will receive an allotment for following us on twitter @sensusmobile, and you will also receive SNS for asking or answering questions on the app during this round of testing. Currently, all SNS/USD in the app are valueless test-net currencies. However, once the ICO ends, all test-net currency balances will be erased, and for every question you asked or answered during the beta, you receive 1 proportional stake of the 500,000 true, cash redeemable SNS set aside for beta testers. Depending upon how many people participate in the beta and how much testing we need, we may also run a second testing bounty with a greater allotment of SNS.
