Our friends over at the Hand Eye Society started a Beta Buddy Program. What is the Beta Buddy program you ask? It's a program to sign up to be a beta tester to test out unreleased games, or if you're looking for beta testers, you can sign up for the program as well to get testers:

"Interested in playing games before they’re released, and telling the game creators what you think? We can help you out. Want people to play your game and get their feedback? We can help you too! We’re starting the Beta Buddy Program to help game creators get the feedback they need, and provide an outlet for people who want to contribute to and get insight into this iterative creative process."

If you want to sign up to test out games, you can fill out the following form. If you're an indie developer and want to have your game tested, you can fill out this form. Make sure to check out The Hand Eye Society for all the details.
