OK people get hurt in the pit. Thats to be expected. There ARE however SOME rules to be followed. Simple little rules that everyone SHOULD know. Here they are:
1. If someone falls in the pit, PICK THEM UP. Do not kick them, step on them etc. Have the balls to help them back on their feet, then keep dancing.
2. If someone wants to leave the pit, LET THEM. Its much more fun if the people in a pit ACTUALLY want to be in there.
3. If someone gets hurt in a pit, STOP and help them out if your next to them. Be a hero, maybe someone will buy you a beer for it.
4. DO NOT bring in things like skateboards. I have actually seen people do this. I have also seen people get pissed of when someone takes their board and breaks it in 2. Get a clue.
To sum it up, just use your head. Don't ruin the fun for the rest of us...there are more of us than you, so don't be an asshole.
