OR, I'll address your last point first. I am in such a different place these days that I haven't figured out what it is or how to talk about it. It is a good place

, but maybe it has just been so long that I'm not sure how to handle it right now. Plus, I have been busy with work heating up and doing things around the house. No excuse. I'm glad I moved out when I did though, I've been so busy since. One of these days soon I'll start posting more again, but probably in a different vein seeing as how I'm literally in a different place now.
As far as teen discipline goes, I think every child is different, but here are somethings that helped with my daughter (16 now):
Consistency. Consistency. Consistency. You have to prove to her that you are more stubborn than she is.

Setup the limits and rules clearly beforehand. You will probably hear "Well you didn't say I couldn't..." (technically do what I really did understand you wanted me not to do but I wanted to do so I did it anyway.) Ask her if she has any questions about where the boundaries are when you set them.
Always tell her you love her and are trying to teach her. Actually, this should probably be at the top of the list.

Tell her WHY you are setting a limit in this area and what your concerns or fears are. Sometimes she may have valid information why that is not a problem. Most of the time she will think she has valid information why the boundary is not needed but you will not agree.
Stick to your guns and tell her the rules and that you love her over and over and over.... If they haven't already, hormones will kick your daughter's brain out of her hear for a couple of years. Don't worry, it does eventually come back.

In our case, my 12YO daughter just could NOT understand why we had a problem with her hanging out with a couple of 15 YO boys with a friend of hers and trying to hide it from us. No matter how many times we explained, she didn't understand and thought we were being so unfair. She did finally realize when she was about 15 that it was actually not OK for 15YO to be hanging around with 12 year olds and that was so uncool.
Keep what works and change what doesn't. Mainly, just keep talking with her and let her know that you aren't just out to keep her from having fun, but that you want her to be safe while she has fun until she learns (from you) how to keep herself safe.
I'm not sure if any of this helps. You know your D better than anyone else, so I say trust your judgement. Just remember that over the next few years she will start to become more independent. The real trick then is to separate when to hold them back for safety and when it is just you being nervous and learning to sit with your own fear while you let her go somewhere new.
Sigh... I still have a lot of work to do to learn how to post short posts.
