You can now register/sign in to 4P with your Steam account using the following instructions: If you're a new user that hasn't registered yet, click the Steam button next to "Sign In" in the navbar. You'll be redirected to a Steam page where you can log in. If you are a current 4P member, go into your account options and click "Manage Steam" to go through the process of linking your Steam account and your 4P account. If you have linked your account, you can sign in through Steam at any time by clicking the Steam button on the navbar or "Use Steam" on the Sign In popup. In the future we hope to integrate Steam even more by including your achievements, activity, and the like!
