I've seen some pretty rude things going on but I imagine half of them don't even know they're being rude. So here's a few tips to make your "no hard feelings" really make no hard feelings.
- Be courteous of your opponent. Please don't constantly complain about your lag in a match. Your opponent may perceive this as an attempt to make him drop his guard.
- If you lose, please don't blame your lag, lack of sleep, people talking, etc. Your opponent won and saying anything other than "congrats" is basically saying "You have no skill, I would have won if not for <insert excuse here>".
- Please do not blatantly insult your opponent before, during, or after the match. Trash talk is fine but you can usually tell when it crosses the line and becomes insulting.
- If you win, congratulate your opponent. After all, they showed up and played you. We've had quite a few matches where an opponent was so scared he/she just quit. At least they gave you the respect to give you a good match - please give them the same respect.
- Please don't insult the players if you're a spectator. Odds are they're going to see the match on YouTube.
- Please show up for your matches. To just not show up tells your opponent and your referee that you don't care about wasting their time. If you're going to withdraw, please formally withdraw and do not waste everyone's time.
- Please don't spam the referees. We are not going to give you the password, we are not going to recite all the tournament rules to you, we are not going to tell you when you fight, and we are not going to tell you when others fight. We have threads for all these and if the room is locked, its locked for a reason.
- Spectators, please don't spread a password to a locked room. The players have invited you - not the entire server. It defeats the purpose of locking a room if you go and shout the password after you're given it.
- Please don't share information with the players. If you're watching please do not tell one's MP status, etc to the other. If this becomes a problem we'll just disallow all spectators.
- Please don't rush the referee. If they're taking a minute or two to share information before a match starts, it's for a reason (usually I asked them to). We do things for the good of the tournament overall - not to hear you whine that we need to hurry up.
- Every now and then, why not thank a referee or the players? The refs donate a lot of their time to this and without the players, there wouldn't be a tournament at all.
Just some tips for being a better sportsman and a better player. A player who's respectful and a good sportsman earns much more respect than a rude, arrogant, pushy, sore loser/winner.
