Writing to Jane?

I wrote about this when I filled out my first “what did you mail today” form, but with that tab currently hidden from view on the profile page, I don’t think anyone saw it. I would LOVE to write to Jane, but I’m nervous. Not having much experience with letter writing in the Regency and not having created a Jane Austen spell-check dictionary myself, I’m afraid that my style will be all wrong or that I’ll use words Jane wouldn’t know. And then there’s the problem of figuring out WHY I’m writing to Jane. This probably seems silly, but I keep thinking I know all kinds of things about her but Jane doesn’t know me at all so what excuse do I have to be writing to her? Any advice/suggestions?
