I also think that a signature campaign is not a bad idea. You have to invest some money to run the campaign, but in the end you can bring in a lot of new players so the long term should be profitable I think that way. Many other sites have done this as well, especially in the beginning when they were new to the forum. I also think you should be active in offering promotions in the games and rounds section.
that is not bad idea because signature campaign is informed of advert and a promotion of a particular site so why all this signature company existing in a service board is because they are looking for multiple promotion with the help of the signature people go through airside and no signature campaign over the service board is not having what is promoting and through there people is assessing what they are promoting
