Sarah, you have to start your own chatroom.
A few weeks ago I PMed a few posters who were decent people and had similar styles like mine and invited them to make up a chatroom. Most of them declined for various reasons (not willing to share their strategies, distraction,etc.) but 1-2 gave it a try.
Now I have a friend with who we can share ideas, talk about mostly the market and so on. It takes time, but if you advertize your style and what you are hoping to achive in the chatroom (beside chitchatting about movies) you might find similar people...
