You have the option to keep your Image Logo visible, without the need of your sitename. To do this:

1. Select the Design tool in the gray navigation bar.

2. Click the Header & Logo option under the Sitewide tab in the right-hand menu.

3. Be sure that you have an image as the logo, and to remove the website name, select Do not include. Or select a position for the Sitename if you would like it to still appear. 

4. Select Save and Publish to take your changes live!
