so which section I have to improved and made posts please
Most of the merited posts are on Meta but it doesn't mean that you have to post only there. As long as your posts are connected to the thread/topic, section and has helped many people, you will receive unexpected merit from them which means you can post in different sections that you are knowledgeable. If you are good with technical terms that's better.
Anyone with a low status at the BTT wants to get a higher status, but this is almost impossible. I know 2 users of the community who create only quality content and for 6 months no one has received any merit.
Who are these 2 users?
