Verifying through your existing Facebook works. :) Don't over do the self-voting too by the way. It is frowned upon in replies especially. I rarely ever self-vote to avoid that issue entirely. Your votes are how the daily crypto is distributed. The more Steem Power a person has, the more of the crypto being given out they control. When you upvote therefore, you're giving it out to yourself. People who do that a lot are usually heavily ridiculed.
