Below are some useful websites for students and licensed jumpers to help with training and education:
USPA.ORG The U.S. Parachute Association, lots of good stuff on their website.
SkydiveSchool.org A great tool for preparing for your first skydive. Self study to become more familiar with the equipment and procedures ahead of time!
dropzone.com Good classified section, be careful in the forums! You can get good info and bad there!
