FWIW, I haven't made as much use of my blog as I thought I would. I then found there was this email option, which would allow me to email my entries to it. So I go to the docs section, login to my blog, follow the instructions to go to "Options", and then to "Write", only to find there isn't a 1-to-1 correspondence between what the docs say and what I've got on my wordpress-hosted blog. It doesn't have the "blog-by-email" option in Options>Writing.
What is the situation? What should I do?
