New Lecture Notes Page

Some people have been having trouble downloading the Google Docs presentations, and I've been having trouble updating the Lecture Notes page on Blackboard (for some reason it is not working well). So I'm making all the lectures available in powerpoint format at this link. All lectures so far are available there, and new lectures will be added there as well as to the blog. Please let me know if you have any trouble downloading the lectures from that link.
