Welcome
16 isn't too young to be on this forum - I'm only 18. You are too young to go to clubs, yes, but you have time to fine-tune your skills and practice before you go start going out.
And as for the methods you use - people on this forum use a huge variety of techniques and methods, so they won't get angry or flame you for using another method - some people prefer one method over another, but you can discuss and use any method of PU you like. Admittedly, some methods work better than others, but it's really up to you - what you like doing and feel comfortable with.
And you asked about rules? They're stickied in an Announcement at the top of every forum on this site.
Again, welcome, and I hope you enjoy yourself and learn a lot while using this site
