I have a very good legal method that will get people to sign up at your arcade and write at least one comment. Price: $0.10 = 1 free sign up + 1 comment. I have used this method on my arcade at http://www.wooshgames.com and received about 9 or 10 users in just one or two days. But i did it the lazy way. I will try hard to promote yours so that you will get more users. I won't guarantee that these people will click on your ads or anything but they will definitely sign up, play at least one game, and post at least one comment. Minimum order is 100 signups + comments = $10. I accept paypal. 1 free review of 10 signups + comments
