They mistakenly sent that email. It was for me.
Seriously, when you look in the mirror do you see the person they are referring to?
Enough said.
I guess the positive is he sent a PM.
Ask his concerns and then address them I say. He didn't blast you on the board and trust me blowing people off can only make matters worse, like last week. Keep it real like you do and I am sure your sincere attempt to resolve this PERCEPTION will be successful.
My 2 cents.
