Hey guys i just created new account on steam yesterday for my brother with same email with me. Right now i really forget the account username but i know the userID because i took screenshot in game before i lost the account so the folder with ID appear in my steam folder. i've already use email to get username but the one i got is my username not the on i just created. So is there a way to see Username by UserID ? Thanks
