So there is an inconsistency with the site. Going to www.tableau.com/support/ does not show it.
Vizable is acting like its own product site. When you find your way to the Vizable forum (Forum ) the look is a little different than these forums (personally, I like the Vizable one). Take a look at the breadcrumb there:
If you click the parent 'crumb, ALL PLACES, you come back here to the regular forums. If you click on the Recently Viewed link you will then see the Vizable place:
This is the only way to easily get it into the common stream of forum spaces. The Vizable forum doesn't have a button/link so you need to use the settings icon (gear icon) and click on the Follow link in order to add it to your Following list.
Thanks for the feedback.. This is being shared around.
