You're very modest :-) I don't know if the rules have changed but from what I recall as a Rising Star, the email notifying you of your nomination states that you can promote your hub to get votes by using email, twitter, and fb. You get votes from hubbers and friends outside of hp. I was modest, too, and didn't promote within hubpages because I was still new and didn't know how. I think you can share with your followers though via the hubpage feed. I hope this helps. Congratulations and good luck.
