Is there an advanced social skills platform somewhere?

I’ve got quite a large group of friends and dont have much trouble getting girls but I’m always looking to improve. Being social is the most fun thing in life to me but I also love improving myself and the combination is very interesting to me. I’m just noticing that a lot of the questions on this subreddit are kind of basic to me and while I’d love to give back, I’m not getting much from it. Does anyone know if there exists a more advanced forum?
