We can comfortably advertise in the .COM forum and perhaps the TWC on an individual basis. For example, if I want to participate in the competition, I can post the same story on the TWC while mentioning that this story and more are also available on the ORG. So it is a win-win for both sites. Once the advertisements are out, we will receive more entries.

I think the biggest obstacle is not really participation once the advertisement is out there (and we make it clear that every finished story will win something in the end), but rather how many of the stories will carry to the end. Finishing a domination campaign is a marathon. Two marathons if we want to make screenshots and write about it. Three marathons if we want to make videos about several battles! It will be sad to see 80% of the stories run out of steam as the writers lost interest in the game. Maybe the staff and moderators need to constantly encourage them. :p

I am just a senior member so I am in no place to annouce the competition. But just an idea. If there are things I can help, I will be glad to. For example, I can help posting the instructions of how to upload pictures and link youtube clips.
