Aside from reading the links that are mentioned above, I suggest that you also learn about bitcoin. Like, what bitcoin really is and think about what can you contribute to this forum. Just posting and posting won't help you anymore to rank up since for the Member rank, they are now requiring 10 merits and merits can't be just bought or just earned so easily. You have to contribute something by actually being informative in your answers to the extent of helping a user that it made him/her give you his/her precious sendable merit points. It's easy to get to the "Next level" from being a newbie which is Jr. Member since you only need 30 activities and zero merits but I assume you want more than that, right?

In other words, be involved in this forum and help other people. Also all of these things that you have earned will go to waste if you get a negative trust so don't scam people.
