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.
If you know the market, help people in the community, you earn merits. Not easily but not impossible. It's just that you have to contribute to the community genuinely. If you just do it for merits you can also go beg for merits but you won't get many as it's not really looks good.
