For many publishers ads are the main source of income. We understand this and of course we support every aspect of it. There is a feature to place advertisements directly in the Creator. But we know that commonly there are other sytems already in use. All most used systems are supported. This means you can keep using those systems without any issue. Cutting down the time it takes for you to place advertisements. If your system is not yet supported, let us know and we will add it for you.
