Thank you for your interest in SportsGamer! First off, you'll need to create an account on the SportsGamer website..
https://sportsgamer.gg/community/register/
Follow these instructions:
After you've set up your account, you can now start looking for a team or even sign up your own. We suggest you check our newsfeed and the "Leagues" tab on the main page to determine which leagues are currently running and if you would be eligible to join any of them. Here's how that would look:
Keep in mind that most leagues do have some kind of transfer deadlines or restrictions, so even if they are in progress you might not be able to join in the middle of the action. If you aren't eligible to join a league right away, you can post in the free agents thread here (EU PlayStation), here (NA Xbox) or here (NA PlayStation).
We'd also like to have you on our Discord server, where you can ask for help and look for casual games!
