You can choose to stay in your local for discussions that you're familiar with in your language. But you seem to have an understandable English and I can say that you're better than me so should you join other boards for discussions, don't get scared as long as you don't get off topic.
I have a lot of questions and I don't want to stress everyone with my many questions hence the reason why I am asking for links to useful threads. Thanks for your help.
No worries, ask what you want to ask and check out the stickies first from this section and if you're done, go with the other sections.
If you have limited knowledge on other boards, then you can stay on your own local board and make quality posts there. However, exploring the other boards as well will help you grow in the forum.
