Welcome to the forum; it seems you already made a lot of posts. So the first advice is to read more than you write posts. Unless you spend more time on the forum to read, it will be hard for you to learn. There is a lot of boards; you may visit them according to your interest. A couple of thread lists have been posted on this thread that would help you to learn about the forum. Engage in the discussion if you really need to avoid spamming over the forum.

One more important thing is to always try to use the forum search button to know anything you want. So you may get a related thread that you want to know about. Just engage there instead of creating a new thread. If you are really not able to find your desired answer, then you are free to create the thread on related boards. Try to help keep this forum clean.
