I have a suggestion about this merit system, I do not know if anyone has ever suggested this, if it is already there I apologize.
my suggestion is, if only every new member like (Brandnew, Newbie and Jr.Member) has their own forum place that they can use to try to make a quality post will surely more menguraingi post junk and spam.

after that you can give them merit for the post they made, I think this will make it easier for beginners and new members in this forum.
