I've made almost a hundred posts and yet I have only few merit, what am I doing wrong? Are my posts not quality enough?
Generally, you must make good posts (with good quality or shows that you put your efforts in it to contribute something interesting in the community), and you need another condition which is some members will read your post and have sendable merit to give it to you. Sometimes, readers see your post is good but they don't have sendable merit at that moment and they will move on. Very few members will bookmark your post and return later to merit it, they are likely merit sources.
If yes, please I need corrections and guidelines to grow my account. I truly need words of encouragement and affirmation that am on the right track to enable me step up in the game and I also need you guys to help me point out some of my posts that aren't so good, if there are any, so I can learn from my mistakes and do better.
I don't know what you did in past few months but if you actually spent your time to learn, you will see some pinned threads in Beginners & Help board which is a board you posted this thread.
I believe if you read those pinned threads, you will find answers there. So if you have yet read them, now it's time for reading.
