Adding your shiny new ActiveUnlimited profile to your facebook profile tabs is EASY!
Once you've logged in to facebook, click on the top "Profile" link and then click on the plus (+) symbol next to your main tabs and then click on "Teaching"
(or type "Activeunlimited" and press enter if it isn't available in the list)
The tab should now be added to your facebook profile. Your ActiveUnlimited teaching profile will now be visible to anyone browsing your facebook profile.
Be sure to tell your friends it's there!
If at any point you accidentally remove the tab, you can click on the application button (bottom left of the page), click "Edit Applications", then click "Edit Settings" next to "ActiveUnlimited" and then click "add" next to "tab":
