Please how do I know that I am making a quality post because I need to start posting high quality posts, get merits and leave Newbie zone.
The purpose of making high quality posts isn't solely to get merits, or for you to "leave newbie" like you said, Bitcointalk is a forum for Bitcoin discussion and other whatnots too, so we basically discuss the aforementioned here, so as you discuss with other users and contribute to discussions in places other than the bounty section, users will give you merits if or when they like your contribution. But your contribution shouldn't be because you want merits, it should be because you want to discuss about Bitcoin with others, thus you go in search for knowledge that is required and it becomes a win-win for you in learning, contributing to the forum, and receiving the appreciation for it in the form of merits.
I disagree somewhat. newbie status has many restrictions and if you actually are posting good stuff the restrictions are somewhat tiring to deal with.
Purchase a copper membership is not a solution for some third world people.
merits and leaving via good posts is the only way for some poor people.
