Doesn't this command do exactly the same? Unless, of course, if you were gone for a good while (dunno exactly when this expires), but if you were gone for so long you probably missed the tourney anyways.
Correct me if I'm wrong though, the other tutorials i saw didn't have this command, so it might be outdated.
