Love, love, love this suggestion. As an instructor in a computer lab class, I see the problem frequently. Normally, the asking student is asking another student because 1) the instructor is busy with a student that may be way behind the class OR 2) the student feels you are very experienced and a good source of knowledge OR 3) the asking student may simply want to get to know you better.
