Well, it would be nice even if some don't read it. This way people who like to bash people who post non-modifications in the modifications area have far more of a reason to flame them out

.
Maybe the message can say something like:
"You are about to create a modification thread. This area is designated only for modifications you have made to the Vbulletin software. This
IS NOT the place to ask questions or suggest modifications. If you need assistance with these subjects please use the proper forum area. By clicking the continue button you declare that your thread will be that of posting up a modification that you or a group has created for the Vbulletin software. If otherwise you leave yourself open to our members "flaming" you to tears.
(Continue)........(Go back now and save the agony)"
