Welcome mate, for clear understanding about the forum rules or crypto you just have to read each pinned post but I think starting with meta section is perfect for newbies. How can one start posting is simple, asking questions still depends from your post history it shows you’re posting rightly although there’s still a lot to learn probably if your post is not in the right board the mods will do justice to that, like I stated earlier the forum rules will help enlighten your understanding so it’s better you do more research than writing.
