Dear Kirstie,
Thank you so much for taking care of this -- for helping me correct my error and doing it so graciously.
I can hardly imagine how intense, busy and demanding manning a website on a Saturday must be. Yet, you followed through and helped me. (And may have saved or, at least, preserved the friendly state of, my marriage!)
I hope your employers realize what an outstanding professional you are.
Again, thank you.
Brenda
