You have to earn merit, but it's almost impossible to do it, you can be a most jr.member
You are hard stuck junior member rank if you didn't contribute anything in the forum and just talking nonsense (probably your red trust says that)
It's nothing. I wrote 30 posts in 2 days. on day 3 I was given the rank of J. member. My friend wrote 60 posts in a week, he was given a membera in 2 weeks.
Just look at your merit, it's "0" and yeah it's nothing. Since merit is a subjective thing, you can't blame the people if you do post a garbage one.
