Just make a fake one for the game, that's what a lot of people have done. Nobody wants to use their real life info. My twitter is @flagm_v4, it shows nothing real at all and I only use it to talk with the other gms about the game and chat. It shows my profile name as brandon lee, pretty sure Bruce lee isn't my dad 🤣
So it's 32 gms each person owns a team and has a cap friendly page inside our cap friendly forum. We do everything a real gm would do for the team, trades/waivers/draft/call-ups/send downs/ltir/cap compliant. We are currently in the playoffs and the draft lotto just happened. 6/25 is going to be real draft based off this current draft class
