There are two ways to share. Right under the name on the left of a hub is the sharing area, with the different places you can share with Facebook, Twitter, and HubPages Followers. Click on the button for whichever you want to share with. Also on your feed, below the comments for the hub, is another 'share' button. That one will share with your followers on HubPages. You can also copy the link and paste it if you want to share with a place not listed. It is not legal to copy and paste the hub any where else.
