Playing the game and posting it just to show off... that's stupid, and trying to prove something to someone...

First of all, this isn't for show; secondly, no one wrote anything about your skill. It's all so that you understand how things work here, so that when you challenge someone to a tournament game, they don't have to explain to you where to get Hamachi and how to play through it. In the end, you can write to the judges in ICQ and find out in more detail why you weren't selected.
P.S. Heroes is already a thing of the past, but as you can see, people still play it, so talking about ICQ is inappropriate here. And if you want to relive your youth, play a fun game instead of stirring up trouble in the tournament thread, and everything will be fine; I think you'll definitely find someone to play with.
