As far as I know, you can write a hub promoting your hub. I found this out, when I ask HP if I could send email to my fans about one of my hubs being a HubNugget Nominee. The answer was no, I couldn't mass-email even if they are my fans. But it was suggested that I could write a hub promoting my nominated hub. I hope this helps. But this helps too.. now I'm off to read your hub.
Happy New Year!
