I read the other post from newbies asking about how to join a campaign, can newbie join a campaign and is there a campaign for newbie.

So what is the best thing to do as newbie, is it finding a campaign to join or learning first until we become a Jr member?
Because in my own opinion much better if we should learn first here before joining. Since we are newbies our knowledge is not enough to make a quality post. This is just my opinion.
What can you say about this?
