"Artists Beware"

For the second one, she's taking quite a bit of time, but I wouldn't go so far as to say she's ignoring your note since you only noted her today. While much more proffesional to reply to you, she may mean to reply later and had other things planned. Or, still not the most proffesional thing but human, she may have put it aside for a minute, got distracted and forgot. I find I forget about notes much more easily then I do my email, but that's also why I only work through email.

I'd give her a bit more time to reply before doing what others would suggest.
