Im up to 6, and have some more coming. Once you get over 5, you can do some more deals as you please. Its worth it, and its our way to try to weedle out the scammers to make this site good!
I like it. It seems to work. I should be at like 7 or 8 by the time I get home. I signed up for the site while I was here (Israel) and have loved it. It really is a great site. I want to work my way up to moderator.
The reason behind only doing 2 deals at a time until you have 5 feedback is because of some scammers like to complete 10 deals, and then never send his/her end. We wanted to avoid this.
