Welcome to ThyElite! and you should sign up for mycoke if you really are planning on getting into it because it can be very addicting. But if you have things to do ex: a job, family etc.. just leave the gaming to your kids. Enjoy your stay!
It's best to know what your kids are getting into. As for hacking the game, it gets harder and harder as time goes on, but if you know what you're doing, you'll get the hang of it.
