It would have been better if you made the heading like how to get merit. Writing it as free merit gives a thought of possibility for paid merit as well.
I am sure that having good English helps you write constructive posts but this is not the compulsory requirement for a quality post. The intentions and attitude of the member should also be considered.
I just used the word free only to get more attention for the topic because I know that this could be an attraction , the message that I'm trying to send is there are a lot of opportunities in the forum to get money easier than trying to be enrolled in signature campaign , when I joined this forum my intention was to get information and get more closer to the cryptocurrencies world but when I understood the purpose of this forum I tried to share my knowledge and my opinion also with others .
