What would be your response?

I am the secretary on the exec board for an organization I'm apart of. This is my second term. I was automatically put into this position on top of the one I was elected to because people said my minutes "were the best the chapter has ever had...at least since they've joined. Yesterday, I got an email from one of our active members. In order to be active you have to meet a long list of criteria. I don't think the girl that sent me the email is going to make it. I forgot she existed to be completely honest with you. I've only met her once. Well, she basically sent me a rather forward, long email making it sound like she's been doing this job forever (I'm not even sure if she's ever been secretary) and that all the things I need to do differently. most of which I already do. One of her complaints was I need to take into account people that can't come to the meetings. However, alumni that, obviously, never come to meetings have said reading my minutes was just like sitting in a meeting. The one thing I sometimes leave out is a contact person for every event but that is only when it wasn't mentioned in the meeting because it's understood the person will contact the vice president of that depart (i.e. fellowship, service, etc.). She also told me that I can get the binder explaining all of this in our organization;s cubical. I've held this position before, and was told there was no binder for it?? I'm not sure where all of this was coming from. Like I said she hasn't been to anything, and I thought her email was rather rude. I don't mind criticism. I work 2 jobs and am a student; I'm used to it. However, it kind of sounded like she was hating on me, and I don't know why???
