I am back now and I hope to remain a disciplined member of this forum and also help newbies with the few knowledge I have.
You left from forum for almost two years based on your wishes and you returned today, based on your wishes too. Nobody forces you to left and come because you can make your own decisions unless your account is banned.
Ideally, a forum can help anyone to find out about bitcoin and others based on the knowledge, experience shared by users. Depending on your goals, you will not be prevented if you want to advance and improve your ability and discipline to post something that is useful both for you, other user and forum. So welcome back to forum.
