Jr High Volleyball: What is the serving line?

Question
What is the seving line in Jr. High volleyball?

Answer
Good evening Julie!
It's great to hear from you!  
The serving line is the endline at the back of the court.  
You cannot step on it until after you have served the ball.  If you step on it during the serve, the referee will blow the whistle and point to the line.... so you know you had a "foot fault".  
I don't know if I answered your question or not.  If I didn't, please follow up.  
And, if you get your parents' permission, please visit us at www.coachhouser.com.  We have club teams, give lessons and direct camps.  I think you'll really enjoy the smiling faces!
