You can use your company's logo and banner text to provide a consistent look-and-feel on your Quatrix site.
To customize your branding:
Go to Administration → Service Settings → Appearance section.
Upload a .png or .jpg version of your logo that will appear on the login page of your site as well as on every share. Make sure that the image is less than 1 MB.
In the Company name field, type the text that appears to your users above the logo on the login page and in every email next to the logo.
Add corporate signature that will appear on every share.
You can format your signature using basic formatting options.
