No. I didn't take Latin, and I have since regretted my decision very much. I only know a few phrases, like "sic transit gloria mundi," and, "nemo me impune lacessit," and, "epistula non erubescit," and, "Freckles locuta, causa finita."
Yes. I believe in capitalization (and therefore had very mixed feelings when I came across a letter-to-the-editor by C.S. Lewis, in which he argued that it doesn't make sense to be particular about spelling in English, because English spellings are illogical...).
