Where did you read that? This place is all about opinions, any one can have one and is welcome to express it. Of course if you start talking about something it sounds like you have no experience at you will not be taken too seriously and possibly get called on it.
Like say you have a thread saying you have never used a bow before and ask what you need to get set up and all. Then a week later you are on here giving tuning advice to someone that is having problems. Some may say you have no buisiness answering at all, but if it is a question on something you actually delt with and worked it out by all means share your experience.
These sites are not any fun without interaction from the members (regardless of how new they are), so post on anything you want. Some come here to learn, others come here to share thier knowledge, and others yet come here out of boredom just to stir things up[
].
Welcome aboard, glad to have you regardless of why you came here.
