The PkgAds platform always supported white labeling, but it wasn't available for the public. In today's update, the white labeling functions have been fine-tuned and tested, and I've written a page about the subject: http://support.pkgads.com/pages/white-label.html
In addition to the above post, I've fixed a few bugs related to the Demo functionality. First time visitors can create a demo account to preview the platform.
