Hey Bitcointalk fam! 
So, I've been aware of this community for like 4 years now, just kind of hanging around the edges.
Welcome to the forum, since you have been hanging around here for like four years, am sure you will now understand the forum rules and regulations, know that if you go against any rules, then you are going to be punished, so try and abide by the rules and regulations of the forum. If you are really ready to learn here, am sure people are here which are ready to guide you, just ask about anything you don’t understand. So, I've been aware of this community for like 4 years now, just kind of hanging around the edges.Op 4 years, that is a complete waste of time without Leaning much, assuming within that time you spent on the forum, you learnt some things it would have prompt you to sign up earlier, because then you'll know the worth of this forum.
Must you sign up on the forum before you can learn? I don’t think so, the OP might be getting all the necessary informations which he needs without creating a account here, if the Op says he hasn’t been visiting the forum or learning anyhow here, I will have said it’s a complete waste of time, but since the OP is learning, then I don’t have any problem with that. Even if the OP created account and doesn’t have any reasonable thing to post, So visiting the forum without creating an account here is not a bad thing.
