i sometimes go through the c/c++ forum and change code tags, but i don't do it regularly.
the problem with current efforts is that it won't help any newbie get an answer. many newbies come for homework, then leave, never to be seen again. the only solution is to tell each newbie beforehand to put code tags on his/her piece of code.
i suggest a better front page. when anyone goes to cprogramming.com and clicks on "Board" or "Forum" or whatever, they go to another page which warns them what to do and what not to do.
we don't need to warn them. we need to make it known that a mistake in that arena will make their future uncertain. we need to inspire such a fright into a mind that he/she doesn't quite turn away, but the words:
are imbedded into the retina of the viewer.
