Congrats! I got 0 Merits during my first month here, and you are already close to 50 in that period of time, so not bad at all. To rank-up at the rate one would have done before the Merit System, you need to earn an average of a merit per day (a bit more of a push is required at the end), and you are already above that average …

Normally, moving from one rank to another get a bit tougher the further up you go on the rank-scale, as it is not easy to have the time and commitment to contribute to the forum for an extensive period of time.
