I have found the professor to return my call right away, when I call him, or e-mail him. I also get frustrated when the web site is down, and always call about it. I post every chance I get, and do the readings, which take me a long time, because of vision difficulty, and sometimes feel frustrated, but not because the professor isn't doing his job. He was online for two chats, which he posted the notes, and gave us the information for the test which I am going to take tomorrow.
Good luck to all of you.
