As a commish, when leagues auto-renew (which is a great feature) there is no way to know if the owners actually committed. I wish the owners had to at least confirm that they are participating.

It was better in the past, when owners had to at least click to respond. Now, no one knows who's still interested, so we don't know whether to institute a search for someone new.

You can contact them via email. Not very difficult task... hold a roll call via email and those that don't reply by a deadline lose their spot. Easy done.
Of course, cut them some slack for a few extra days if they are good owners. Don't want to get too strict either.
