@girish bingo! i will practice once more to confirm but i suspect that the first user == the user that gets rights to previously created things
one other thing i need to double check - when i upgrade to 2.0, for whatever reason (possibly unrelated to the upgrade), my n8n stopped working (it stopped responding to webhook triggers), i will see if that's consistent and perhaps related to "it won't work till the first user is created" or something else
