Issue with the WRINT class's Change in Teachers for 2 1/2 weeks

Hi, I just got a comment in my guestbook--Gmail had put it into the spam folder, but it was from Nov. 11th. Here it is:

I don't like the exchange teacher thing. Why weren't we informed before it happened? Students do have the right to have a comment about the teaching plan, don't we?

So I have replied in this way, and posted it here so you all will have a chance to read it.

Hello, well, I can give you a couple of answers. First, you WERE informed about the change--nearly a week before it happened. I posted the information very shortly after class on Halloween, 10/31--because that was when Guan Shr first told me about the idea. I didn't know anything about it until about 3 PM on that day; I told you as soon as I knew about it.
If you people had done your homework--namely, checking my homepages regularly, as you should--you all would have known about this sooner. Instead, it seemed that 100% of the students were surprised about the news. Why was that?
Second, yes, you do have the right to have a comment about teaching plans--and you have just made one. Thanks for the comment.
If you want to explain more about why you don't like the change, please do. I don't know what the teacher is doing, but I know it's some sort of teaching experiment that she is required to do. Anyway, it won't affect your grade in my class, and you won't get a grade for her class either, so what does it matter in the end? You need not participate unless you want to!

• I hope you'll willingly participate in her experiment, but if you choose not to, it is your right to refuse; I am not requiring your participation, and I am not calling the roll these weeks. Do what you wish, but do please show respect for Guan Shr and her project, no matter how you feel about it; people with no manners do not earn any respect for themselves.
• Finally, why am I getting these questions, anyway? I already answered them in class on Nov. 7th.
  

Thank you anyway, mysterious student, for sharing your objections with me. I appreciate that; so many people are silent. Please share more info if you want to do so. Is something shocking happening to you? What, in fact, is the matter?? If you want me to make up 2 1/2 classes for you myself, I am willing to schedule make-up classes for you, as long as it fits into your schedules and mine. Let me know.
