You may wonder why I'm posting in the women's section of the forum... well, I don't know why either - but I finally found something I can answer.
I used to do cleans all the time when I was playing ball... good for explosive strength.
The best tip I can give you is to POP your hips as the weight passes (right between the dead-lift phase and the explosion), and pull up and back like you're trying to throw the weight through your ribcage at a slight angle. Maybe that doesn't make sense... to put it another way: try to make the weight hit you at your sternum after the pop, while still maintaining an upward pull.
You should be able to pop it hard enough that it will carry upwards while you drop underneath, shoot your elbows forward, and catch the bar with your wrists bent back (and possibly your delts, if it's a very heavy weight for you). Then, the hard part is to come out of the squat (if necessary) and return to standing. If you add the split jerk (easier than the parallel jerk, IMO), it's not really that complicated - just make sure you lock out before you try to bring your feet back parallel.
THE BEST PIECE OF ADVICE I CAN GIVE YOU:
If at ANY time you feel as if the weight is going somewhere you don't want it to, or that you can't control it, DROP THE DAMN THING. It won't break the bar, the plates, or the platform - but if you try to hang on to it, it might break you.
Good luck with a GREAT exercise.
