I do recommend that you should visit your corresponding local boards first if you have any question about the general forum for easier communication. If not, you can navigate through each board and read the topics. As such, if you have some knowledge to share, feel free to comment on your chosen board as this is a forum after all.
Thank you qwertyup23. I think that most new users overlook this option, perhaps due to lack of attention, or maybe because they think that the quality of the conversations will be better in the "North" (aka General board). But the fact is that many of the best posters here are active in their respective local boards too, and many interesting topics have already been translated, too. So yes, starting your Bitcointalk journey from the local boards is some of the best advice you could've given.
