Umm, i first learned about TFP through my SO, because he's a regular here. You can always tell her about it, but just not let her know what your username is. Sometimes you will find out more about her that way because she might be more honest if she would ever reply to one of your posts.
Be warned though, if you use TFP as a place to openly express yourself, be sure that you are comfortable with her knowing who you are. Good luck
