Great site. They also have an "Auto Invite" system that'll grow your mob for you without you having to type your code. It's the largest listing of unique, verified invite codes (60,000+ the last time I checked) as well so you can get tons of people in your mob. If you create a free account all codes you enter will be remembered each time you visit the site too so you don't have to worry about entering the same code twice. Distributed by Tubemogul.
