At least one of the people involved in the incident said some really nice things in my defense. Something along the lines of I've never stood anyone up for anything or lied about anything so if I say I didn't sign up, it's sure I didn't sign up.
That's super validating. Still I wish this hadn't happened and it points to a glaring hole in our process.
But this is the group that doesn't listen to me so that won't be patched up.
