There is a lot to learn in different boards on the forum, and while it is advisable not make comments in boards where you have little understanding, reading through topics in those boards can help a lot, it helped me, and I am sure some other people too.
Maybe beginners and help will also help but being in this forum I think Bitcoin discussion section is the best one too. Other boards will follow when the users are able to know some of the details and knowledge he supposef to learn.
Going outside is good maybe in few months they can engage and learn some on other heaby boards about bitcoin.
