Board Game Arena

I can't figure out how to open my tournament. I have tinkered with 'Tournament starts' and 'Registration starts X days before the tournament starts', putting the date in the past, today or future. I have made it private or public, fewer or more players.
No matter what, I don't see a registration link and the tournament stays in "not open" mode.

Any help please?

You must "Launch" your tournament. Look on the right side in the "Admin panel".

Thanks it worked now, in a new tournament. I'm fairly sure the button was just not there in a previous try

This button has since been changed to say (in English) "Start" and some explanation is now provided.
