... unless you think only the instructor has the answer.

I've noticed that recently lots of the questions in the forum were addressed directly to me, which is perfectly fine if the question is about clarifying the assignments, or dealing with server problems on CS3, and so on. However, for technical questions like hibernate mapping, understanding CSNS code, debugging etc., you should not address the question directly to me (or the instructor of the class) because it's not an effective way to utilize the forum. The instructor may not be online 24/7, and other people (including your classmates) may very well have the answer but would be reluctant to post it because the question was specifically address to the instructor. And of course, even if the question is not addressed to me, I will answer it when I see it (assuming I know the answer ).
