I say if he asks a question you think a student pilot might ask, reply
to the lurkers that have the same question. Maybe Mxsmanic won't get
anything out of it, but someone who truly is interested will.

I understand the frustration, but remember he may ask the question, but
others with the same question may be reading...just a thought.

As a current student pilot whose learned a good deal reading the
responses to MX's posts, I concur with you 100%.
