  • Hi Mathieu
    I was wondering what would be your solution for network content?
    Let's say that Maria poker/bingo etc share the same promotional materials with other gaming sites.

    Would be content re-write is the only solution? Then the benefit of having network content is basically ruled out... what do you think can be done? How would you customize common content without rewriting it?
