A few days ago, I noticed a non-ladder 2vs2 game, klicked on it, and saw a single newbie player within the slots.
I did not join. Two days later, I thought it would be good to help a new player, but the game was no longer listed. I hope that it was simply because all slots were filled, but somehow I doubt it.
Maybe the game list should flag games created by newbie players, so that newbies can be helped, instead of having their games vanish without a trace or notice?!
