See, how the attitude of senior members welcomes your arrival. They are very open to every new member who joins the forum by directing to some important topics that can help your development while in the forum. Some of the links provided in previous comments will be very helpful in exploring the knowledge spread across the forum. Now all you need to do is understand the basics like preventing any bans and to keep your account reputation good, after this you can move on to the level of improving the quality of your posts to get merit as a requirement for rank up in addition to the number of activities.

it's not something strange, we often see things like this in the forum. come to make a thread then leave. maybe will come back after a few weeks, months, or years later. then repeat their questions.
