As a newcomer here and at the risk of leaving myself open to the "you're exactly the kind recent addition we can't stand" criticisms, it strikes me that in terms of etiquette the best place to start for anyone wanting to contribute is to actually read/follow the thread. Figure out as much as you can on your own before clogging things up or breaking rules and spare the people who've been in here the longest from the absurd, or even the not so absurd but it was answered 3 posts before, questions. Know this obviously isn't possible for everyone but the attempt, I imagine, goes a long way.
