I found a free Advertising site Trust very good A+,If your game is not picking up members.then you most likey need to get the word out.Heres a cool site,that does it all for free.plus there are side game built in where you gain points.
They also have Peel Away Ads you can add to your site.
I rate it A+,trust me I paid over $1000 for advertisement
