I always keep the nomination pages on my watchlist, so it is generally unnecessary to tell me that you have responded (unless you responded more than five days ago and I have not replied).
For FLCs that are eligible to be closed, I usually return to the nomination one or two days before the scheduled closure days.
I will only support (FLC/FAC) or pass (GA) if I feel that all my concerns have been satisfactorily addressed and/or responded to.
