What is that they are not understanding? It is as simple as anyone can understand. Post on this forum to increase the activity and earn merit by the forum members for the quality post and rank based on the merit and activities achieved.

As you said, some people are going here and there and not focused on what they are doing, and not reading the pinned posts in the forum is making them not understand anything.

And if you are actually looking for earning in this forum, first read and post good content and increase your rank. Later join some signature campaigns and look for some bounty programs to earn from that.
