I started the Old Norse course about a month ago and I'm enjoying it. I'm on lesson 5. I'm wondering if anyone has also studied Old English. I read in the Saga of Gunnlaug Serpent-Tongue, Ch. 7 that "the language in England was the same as that spoken in Norway and Denmark" before 1066. I assume the writer means that an OE speaker could understand an ON speaker, and that he is not simply referring to Norse-speaking areas of England, but it's not clear, at least to me. Anyway, I'm actually more interested in Old English, but I like this course and I did not see anything similar for OE. But I noticed on Amazon.com that Old English dictionaries are cheap and plentiful, but that's not true for Old Norse. So I was thinking that if I continue to study after I complete this online Old Norse lesson, I might buy materials for OE and start over, with the idea that I will have gained a bit. Am I fooling myself? Has anyone done so and what is the transition like?

Also: how necessary are personal pronouns? It seems like the verb does the job.
