You'll have a PUBLISH button at the top of your article. Press it when ready. You can also go back and edit the hub anytime by opening your hub and clicking the edit button. After publishing, you can preview your hub with all its ads by selecting preview. Then you'll need to go to your contacts list on MSN, Yahoo, Twitter, Facebook, and everywhere else to get an audience. Of course you need to send them the link to your hub. Hubpages makes this easy on some sites by giving you a once click to your sites which publishes for you. To send the link in emails just preview your hub and highlight the link at the top of the page, copy it, then paste into any emails you send.
