>>793374You know how to start a thread and how to post, that's pretty much all you need. You may want to familiarize yourself with board culture, but you don't actually have to, nor do you need to "lurk" for X amount of time before you are allowed to post anything.
But two things. Fist, don't believe anything anyone here tells you. Period. Second, what comes around goes around, even on an anonymous image board. Be nice and you'll meet nice people anywhere.
