Welcome,
After you have read the pinned threads and other threads for newbies in this section. Next, set your personal Bitcointalk forum goals. Below are the 3 questions I asked and answered myself when I first started:
1- Why am I here?
2- What do I hope to learn and achieve in 6 months on the forum?
3- How do I plan to contribute positively to the forum as a member?

If you can answer these questions truthfully then, you are on your way to becoming a valuable member of the community.
