I have barely scratched the surface of what the new widget engine for but at least I have found a use for the TextBox.
When updating the Envision 1.0 theme the widget engine uses the entire right column and to keep the CSS simple I removed the disclaimer text. This text was inherited from the amendments made by Jesse Foster at GravityCube.net.
The question is if you want the text back you have 2 options (well maybe more)

Sign in as admin and select TextBox and click the Add button, you should have something as shown below :

Now click edit and put in the text you want.
