Inner Game Tapping
I found this website after I stopped studying pick up but I still found the videos and articles useful for regular social anxieties.
Welcome to TATLife - the home of Tapas Fleming and the Tapas Acupressure Technique
This isn't a pick up website but it teaches the very best technique I've ever found for getting over issues, limiting beliefs, and trauma's; all of which result in social problems.
Those are the two website I wish I found when I first started learning about dating.
