I don't know the exact reason why do you want to rank up so bad but I think it is already provided at the top of this section specifically those pinned threads. All the answers you seek are already provided there starting with the rules and regulation for this forum, gain merits for you able to rank up, and more. My advice is that the first thing you need to do is to learn, be knowledgeable and gain experience because they are the most significant factors for you to be able to participate in a particular discussion. Upon those discussions, if anyone likes your thoughts and finds them useful they might probably give you merit which will allow you to rank up. To put it simply, you need a foundation which is knowledge, then everything will go smoothly including achieving a high rank. Anyway, welcome to this forum and I hope this comment of mine would be helpful.
