For now, let's keep these rules simple: This is a serious topic for serious airsoft players and event organizers. People planning and hosting events have the sport in their hands. Without them, we're all doing team practices and wondering when something cool will happen again. Don't waste their time. If you post here, you absolutely must take the time to write well. That will help others understand your idea, and it will help convey that you're actually given this some thought.
Have a forum warning for ignoring the rules.

Have another warning for ignoring the rules. Take a look around at the rest of this place and see how everybody else posts. You're not the only person who we ask to use complete sentences, punctuation and capitalization. The reason? Your first post was utterly incomprehensible, and your second just barely shed some light on your quarry. If, on the other hand, you had expressed youself clearly, you'd have received some helpful replies rather than the scorn of angry moderators.
Also Spray, check rule 7 out on the link puggy posted up.
And, I'll answer your question. Waivers aren't really worth the paper they're printed on, and I'll tell you why.
If I go to an event you host and I sign a waiver, and then I somehow get hurt due to negligence on your part, you can bet your ass no waiver in the world is going to prevent me from suing you. And by not having insurance, I would be suing you directly, and probably take you for all you are worth.
That is why it is very dangerous to host events with no insurance. At least with the insurance, if they sue, the insurance will pay it, not you.
So, if you want to invite a bunch of people over that you don't know and have them running around and shooting at each other, go ahead. But don't say we didn't warn you.
