Forget AMM and RHP, like most people said they are a waste of time, too many time wasters on there who get off chatting to you in msn then when you say lets meet up, you get all the excuses under the sun. Vising LPs is definately a must, we did it out of curiosity 6 years ago and still go there and have loads of fun. It is a no pressure environment and most people are pretty friendly, but you do need to make the effort and go and chat to people and introduce yourselves.
Hope to see you there
