I am trying the email verification function of Meteor, following [Meteor #20: Verify an Email with Meteor Accounts](https://gentlenode.com/journal/meteor-20-verify-an-email-with-meteor-accounts/42).

I have some questions about step 3 and 4:

1. In Step 3, `Accounts.sendVerificationEmail(user._id);` doesn't work, while `Accounts.sendVerificationEmail(user._id, user.emails[0].address);`works. Why I need specify email address explicitly?
2. In Step 4, should I modify "Homepage" in `Template.Homepage.created = ...` to my homepage template name?
3. In the doc of Meteor 1.0.4, I can't find a attribute named "created" under "Template.myTemplate".
So if `Template.Homepage.created = ...` has been deprecated?
Is it right to written as `Template.<myhomeTemplateName>.onCreated = ...`?
4. Is this the best solution to verify email?
