回答1:

When you refresh/reload the page Session values are get undefined. You can get the current user email using meteor.user(). You just have to replace you session.get('email') like this.

var user_email  = {};
user_email.mail = Meteor.user().emails[0].address;

I hope that is what you are looking for.
