I am new to this forum, and I already know to get a high rank I have to get merit,
Well, you already did know what is required to rank but it's not merit alone that will help you increase your rank and that is activity points that you can get by posting to threads or creating threads.
well I've here read some guidelines and some threads related to merit,
but here I want to know directly from the users about what and how many posts can get merit.
It's one step you already did by reading some guidelines. Importantly, guidelines are your tips on what to do to get your posts merit. Anyway, you should ask yourself that why do I need merits? lemme guess, your answer would be I want to increase my account's rank right?. If you are truly reading some of the threads and guidelines in the forum then you know what is the purpose of the merit system. You don't need lots of posts if you know how to be a constructive forum user or know how to contribute in the forum in any way you can.
thank you
You're Welcome and good luck. My advice to you is that don't focus on getting merits alone or else getting merits will become harder and harder. After all, we are not here in this forum just to received or get rewarded merit. Consider opening the thread provided by CryptopreneurBrainboss which will be very helpful.
