the merit really has a hard time getting.You need to create threads that are helpful to people.Only by doing so will you be able to get merit.
Creating a thread is not a must, post is enough as long as the post is useful/constructive/good quality. Indeed the chance is bigger for those who create a new thread but bear mind that users need to create something very useful for the community, at least something new (no other similar topics).
I still have difficulty determining the criteria for quality posts, I found many quality posts but they did not get merit. there is concern in giving merit, if an error occurs then the account will receive red trust.
this cause of merit is very difficult to obtain.
Quality post can be subjective, it might be look so good for you but may not for other readers. What errors you are talking about? Sorry I do not understand it well.
