I remember back when CoH/CoV was going to have real adverts in game as billboards. As a community builder for Homecoming, I think that it would be awesome to have billboard contests on the forums and see if we cannot swap some of those into the in game billboards! I know that they did at least one contest like that in the old times, but I think that seeing it come back would be fun.
Just not sure how much of the code to easily swap out the adverts is still in the game.. If I remember it, they removed the feature before shutdown.
