Hi Neil,

Thanks for all the efforts! We will definitely miss you and fortunately you
won't completely quit from MD :). I'm very interested in helping maintain MD. I
have been working on MD for several years. My employer (facebook) supports me,
so I have time being a maintainer too.

Thanks,
Shaohua
