Not really. There are articles worth submitting but because of user psychology and behavior it will not be posted. My logic is that the user will think: "Well, if you didn't want it when I was ready to give it to you, why bother to return and re-submit it". The software should come in the aid of the user, not the other way around. Of course, you might also take into consideration statistical behavior and think: "If a user will not submit it, then other user will come and do it" but that's really relaying on chance, and not a good plan to bet on it.
