As much as I like Ubercart, I didn't want anyone to know which cart I was using.

I was hoping that I wouldn't have to monkey with any code. I have recently been learning theming in Drupal.

Ubercart makes removing the powered by Ubercart footer messages easy.

First go to /admin/store/settings/store/edit/display

Next, you'll see the options for displaying the Ubercart footer messages.

Finally, select the option to not show any and submit the page.
