We've lost 2 owners in recent days yet neither one shows up on sign up blocks. If an owner abandons the team, they go on the sign up block list for 30 days (I can waive that if needed and have done so before).

The fact their names aren't on that list leads me to believe their subscriptions lapsed. Don't let that be you, keep those subscriptions up to date. Should it lapse and you want back in, let me know.
