Yeah... it's been a while since I've been on the forum... and there's THIS going on!!!

How can you sign up for a tournament and then refuse to participate? I understand that you might not have enough time... But you signed up! That means you agreed to fully participate in the tournament! By doing so, you're letting people down - the Organizer (who dedicates a lot of free time to this), your opponents in the group (depriving them of the chance to continue participating in the tournament), and those who were eliminated earlier (you defeated them, BUT what was it all for?).
Yes, it's just a game, and real life is more important. But you have to keep your word!!! If you said you'd participate, be kind enough to see it through to the end of the tournament!
