What can I do to be able to contribute to the forum?

Is it by reporting fraud, cheating, plagiarism or do I have to make a good post so I can be called "your contribution is great on the forum". I read a lot of posts suggesting contributing to the forum and making good posts.

I've been frequenting every available board on this bitcoin forum in the past few days and I came across a post about the types of bitcoin account ratings. Turns out I was very low-ranked.

It occurred to me that I would challenge myself to be in the highest rank someday in a good and right way even though I only worked as a housemaid.
