Is your question about how to email a page to a friend? If so, you can scroll down to the bottom of the hub where it says "link to this page." Copy the link it creates for you and then paste it into the message of the email.
If your question is about contacting the editors at hubpages you can find the information here: click the help tab on the right hand side of your screen. If your answer is not there, you can use the about us tab in the help section to direct your question to an individual.
