I'm not sure I completely understand the question. If you want to show someone your hubs, send them a link to your profile page. Once they visit your profile page, they will see links to all your hubs, they can then click on these and view your hubs. If you want to send them to a particular hub, go to the hub and send them the link (in the address bar).
PS. You do not need to be signed into or have an account on HubPages to visit someones profile page or hubs. Hope this helps.
