You need some basic stuff reading comprehension and analysis here. Forum is a world of discussion, you just need to read, analyse and engage on some topics here worth your interest. Dont be scared to join some and even ask questions that you are confuses with. The higher ranks will definitely guide you but don't be a guy to ask all of questions, some are pretty indeed common sense to do. You also need to consider studying also not rely on high ranks at all times.
The best way to understand this platform is to spend some time here reading posts and analyze what posts are engaging people interest. To grow your account to new levels, its best to see which posts are getting merits and then try to post stuff like that. Ask something that is already not available on the forum or at google.
