Why do you think you need to do that? You don't need to do anything; you can do that, if you wish.
You could also just read the forum without posting much; this is something that newcomers could and should do more, in my opinion. Sure, without posting, the rank won't budge, but who cares about a forum rank?

In the end it boils down to what your motivation is. In my above statement, I assumed a crypto newcomer that wants to educate themselves. This may be a totally wrong assumption.
But in general, I wouldn't say that anyone 'needs to [...] get merits and leave Newbie zone'.
