Add an iframe tag inside the page you want your affiliates to signup or login like this:
<iframe height="850px" width="100%" frameborder="0" src="https://<yoursubdomain>.<yourdomain>.com"></iframe>

To hide the logo from the promoter page, go to the main Campaigns section, click on the campaign menu and select "Configure page".
Once you enter the configuration page, go to Dashboard section on top, select "Hide logo" and click Save.
