I have been on forums where there is a separate section for "games". These are usually word games that give people the opportunity to participate and post something even if they have little to contribute to the main flow of conversation at the forum. Are these type of "games" a good idea?
the are post producers and they will raise the post count on a forum. They also can help you get members involved with each other and coming back over and over again. The entire forum can not be just those games, but anything that keeps members on your forum longer is a positive thing!
