Why are you in a hurry to rankup? I didn't understand it until after I ranked up, newbies does not know the rules, and if they read those rules, he will know that there are Merits and a little effort to rise and not generate enough posts.
You got 2 merits. You need extra 8 Merits and more participations to get the next rank and so on.
Read carefully, OP was worried about his account rank why didn't rankep up to Jr. Member although he already has earned enough activity and merit as well. He was just need to wait few hours before his account upgraded/ranked up to Jr.member automatically
OP, congratulation for your new achievement
