Good idea, but I can see it now...

RTFHowTo

When I grade papers, along with the RED X on incorrect answers there is also a pg??? referring to the page where the correct answer can be found. The student is required to the answer the question correctly. Does not change the grade of the paper but will insure they know the answer for finals. In the meantime an intelligent dialog about the concept can take place.

So, I see nothing wrong with RTFM + pg#. Most of the times that I see a reply with RTFM there IS a reference to a page, section or something of the sort.

Why? Because RTFM is just an insult
Is this really an insult? I think the insult is being asked to give something to someone that feels they should not have to work to have what they want. Do you think that is an insult?
