Umm.. you should be able to find this somewhere, I'd imagine.. but just for starters:
When you serve the ball, it can't hit the net or it's the other team's turn to serve.
If your team served, and the ball hits the floor [within bounds] on your side, the other team doesn't get a point. They get to serve.
If their team served, and it hits the floor on your side, then they DO get a point, and get to serve again.
[The above two go the same for your team.. you only get a point if your team served, otherwise you just get the ball to serve.]
Winning score is 15, but the winning team has to have at least two more points than the losing team. 15-13, in other words. If it's 15-14, then the game keeps going until one team has two more points than the other.
Remember this: bump, set, spike. When the ball comes to your side [ideally] whoever's closest will bump it (hands clasped together and arms extended) to the person who sets it - this sets up a good position for a third person to spike it. Usually the person in the front right or front center [can't remember which] does the spiking, and the person in front center or front left does the setting, but it doesn't have to be that way. Yes, you can just hit it back to the other side in one bump, or two bumps, or whatever..
You can't hit the ball twice in a row. You CAN hit it once, then have someone else hit it, then hit it for the third time.. but your team has to get the ball back over the net in 3 hits, no matter what order you use. Make sure you don't touch the net while hitting the ball... if refs think you touched it, even if you don't think you did, the ball still goes to the other side. :|
Umm.. what else? Practice 'bumping' the ball.. there's an exact way to have your arms to get it to go in the right direction, and it's kinda hard to get it right [it is for me, anyway].
Your team rotates clockwise.. the server is in the back right corner, and on your team's next turn to serve, you rotate, so front right person serves next.
Hope that helped some.. you did say you know just about nothing about volleyball.
