You would THINK it was with how little people actually post sometimes... but it certainly isn't for VT's contest, and if it is here, it shouldn't be. P.E.A.C.H. is one of the most basic motivations for these contests... because people are going to have to vote to make it work, they are going to have to consider the relative merits of the entries. If they are going to do that, why not do it a little (or a lot) earlier, and give some feedback? Those more selfish but still honest, might point out flaws to increase peoples of their own work (I wouldn't know...).
